Soccer, Hoops Next to Seed Using MPR

As the topic of seeding for MHSAA Tournaments continues to swirl in the air of numerous committee meetings on an annual basis, one of the primary concerns continues to focus on the simple question: “How?”
The MHSAA for years has been working behind the scenes on potential formulas which could best be used as a standardized tool to assist in measuring strengths of teams in a given sport.
This spring, the MHSAA introduced the Michigan Power Rating in the sport of Boys Lacrosse. The Representative Council approved limited seeding beginning in 2019-20 for girls and boys soccer and girls and boys basketball, and MPR will be the metric to determine which two teams must be seeded on opposite sides of District brackets in those sports.
“The boys lacrosse tournament has been seeded since it was added as an MHSAA-sponsored sport in 2005. The seeding is done by committee based on several criteria, one of which was statewide power rankings generated by a third-party website. In the Fall of 2018, that website ceased operation – it was the perfect opportunity for the MHSAA to develop its own data-driven, purely objective ratings system and incorporate that data into the seeding criteria,” said Cole Malatinsky, administrative assistant for the sport.
“The benefits of the new MPR system have been already mentioned – it is MHSAA controlled, simple, objective, and transparent, and it can be used by other MHSAA sports in the future.”
MPR is a computer rating formula similar to the popular RPI rating. MPR provides a way to measure a team’s strength relative to other teams, based on games played against other MHSAA tournament teams, largely on the strength of their opponents’ schedules. MPR is purely objective using only the game results listed on MHSAA.com – there is no subjective human element.
What is the basic MPR formula?
MPR is calculated using wins, losses and ties for games played between teams entered into the MHSAA tournament. The final MPR number is 25% of the team's winning percentage, plus 50% of its opponent's winning percentage, plus 25% of its opponent's opponent's winning percentage.
MPR = (.25 x W%) + (.50 x OW%) + (.25 x OOW%)
The MPR formula can be applied easily to other MHSAA team sports.
What game data is included in the formula? What game data is not?
MPR looks only at results between opponents entered into the MHSAA postseason tournament. Wins, losses and ties in multi-team shortened game tournaments (lacrosse, soccer) also count. Forfeits also are counted as wins and losses.
MPR does not use the specific scores of a game or the margin of victory in a game. The location of a game is not included in the MPR formula, and the formula weighs results at the beginning of the season the same as results at the end of the season. Scrimmages are not included.
Why use the MPR formula?
Different rating systems have been used in the past or have been recommended to the MHSAA. We wanted to have a rating system where the data was controlled and stored in house and could be used for any sport featuring head-to-head competitions.
With its own rating system the MHSAA also can control the different components of the formula, thus keeping the tenets of scholastic competition at the forefront (like not including margin of victory in the formula). Finally, by listing all scores and team schedules online, as well as showing the MPR calculator on each team schedule page, the ratings are transparent and can be replicated easily.
CALCULATING MPR
What are the detailed components of the MPR formula?
You need three numbers to calculate your MPR: winning percentage (W%), opponent’s winning percentage (OW%) and opponent’s opponent’s winning percentage (OOW%).
How do you calculate winning percentage (W%)?
Divide the number of wins by the number of total games played. A tie is worth half a win. For MPR purposes, find the winning percentage against all teams that will play in the MHSAA tournament (MPR W%). Games played against out-of-state teams, varsity “B” teams, junior varsity teams, non-school club teams, and any other non-MHSAA tournament participants should not be included when calculating winning percentage. W% should be an easy number to calculate.
How do you calculate opponent’s winning percentage (OW%)?
Average the winning percentages of a team's opponents. When calculating the winning percentage of a specific opponent, use the opponents "Adjusted Winning Percentage" (ADJ W%). Adjusted winning percentage eliminates all games the team played against that opponent (as well as its games against non-MHSAA opponents).
For instance, if the team beat an opponent with an overall record of 4-1, use a record of 4-0 (1.000) for that opponent. If the team lost to an opponent, use a record of 3-1 (.750). Find the ADJ W% for all opponents, and then take the average. If a team plays an opponent team twice, that opponent’s ADJ W% will be counted twice.
OW% is not calculated via the combined record of the opponents; instead take the average of all opponent’s winning percentages.
How do you calculate opponent’s opponent’s winning percentage (OOW%)?
Use the same process described above, except calculated for the opponents of a team's opponents. This number is much harder to manually calculate, so the OW% for every team is listed on the MPR page of the MHSAA website.
Again, simply take the average of all opponent’s OW%.
How often is MPR calculated?
MPR is calculated about every five minutes. Enter a score and a minutes later the team MPR and the MPR of all the team's opponents will update.
How much will my MPR change throughout the season?
You will see wild MPR swings in the beginning of the season, but after about 10 games played your MPR will start to level out. At 20 games played you will see very little movement with each additional game played.
My score is missing. How can it be added?
This is a crowd-sourced system. Any registered user of MHSAA.com can add a missing score. ADs, coaches, parents, students and fans all can login and enter a score for any game.
What are some common errors when calculating MPR?
When calculating your team’s winning percentage, only include games against MHSAA-tournament teams. When calculating your opponent’s winning percentage, don’t include the games they played against you. When calculating ties, count the game as a half-win and half-loss.
What happens if a game is cancelled?
Because the MPR system works off of averages, it will not make a difference in the final MPR if a game cannot be rescheduled. It would not penalize, nor benefit, any team involved in that scenario.
USING THE WEBSITE
Where can I find game scores?
A list of statewide scores for all sports can be found in the MHSAA Score Center. To find a schedule for any team click on “Schools & Schedules” in the top navigation bar, search for the school, then once on the school page click the sport. You can also see a list of all schools (with links to schedules), on the statewide MPR list.
“We continue to have great success in score reporting for varsity boys lacrosse contests. While we state that schedule submission and score reporting to MHSAA.com are required, athletic directors and coaches understand that in order for MPR data to be accurate, we need consistent and accurate score reporting,” said Malatinsky. “MHSAA.com is now the primary site for high school boys lacrosse schedules, results and ratings in the state.”
How should I use the statewide list of teams and MPR?
Linked to the boys soccer page (and eventually to be added for both basketball pages and girls soccer) is a statewide listing of all Michigan Power Ratings (MPR) for teams entered into the MHSAA postseason tournament for that sport. Linked on the MPR page is an explanation of the District draw formula, describing when and how teams will be placed on the bracket.
The MPR data updates every five minutes. Click on the column headings to sort the data. You also can use the drop-down menu to show teams in one Division, or type a District number in the box to filter teams for that District (Region for boys lacrosse).
You also can click on any school name to go to its schedule page.
How do I read the school schedule page?
The schedule at the top of the page shows the date and opponent for all scheduled games, and results for games already played. If results are missing, click “Submit Score” to add a game score.
Below the game schedule is the MPR Calculator. The calculator is split into three sections. The first section shows the three MPR component scores for the team, as well as the team’s current MPR score. The second section shows the MPR information for the team’s opponents – specifically, for the opponents the team already has played (actually, for games where scores have been submitted). Only these games are included in the MPR calculation.
The third section highlights future opponents. The MPR data for future opponents are not used in the MPR calculation for the team.

Championship Team Builder Ingalls Named WISL Honoree

Krista Clement played for high-caliber basketball programs at St. Ignace High School and University of Michigan. Then, after a few years of teaching, she decided to start her own team.
In 2013, Clement founded Helper Helper – a digital platform that provides tracking and coordination for community service efforts across the country and counts the NCAA among partners.
At first, Clement’s team was a team of one – herself. But as she started to build the company, her thoughts turned to her high school coach Dorene Ingalls – one of the most successful team builders in MHSAA history.
“Although we aren’t playing basketball on the Helper team, so much of what I do was through what I’ve learned from Dorene’s leadership,” Clement said. “My attempt to create a culture on my team – similar to a Saints basketball team – has come from Dorene. I now find myself trying to connect with my team the way Dorene connected with me – making my teammates feel valued and inspired to put their best foot forward every day.”
Over the last 22 years, Ingalls has built one of the most respected high school basketball programs in Michigan and become one of the most successful coaches in MHSAA history. She also has been one of the state’s most impactful advocates for girls basketball, and a presence in her adopted hometown that literally earned her the title of “ambassador” from the local chamber of commerce.
To celebrate her many and continuing contributions, Ingalls has been named the 34th recipient of the MHSAA Women In Sports Leadership Award, presented annually by the MHSAA’s Representative Council to “women coaches, officials and athletic administrators affiliated with the MHSAA who show exemplary leadership capabilities and positive contributions to athletics.”
And as with Clement, those contributions continue impacting many long after graduation.
“To have the confidence to overcome when people say you can’t do something,” Ingalls said, boiling down what she’s hoped to pass on over two decades. “We still always are like the ‘Hoosiers’ coming down (to a state championship game) – we go with that flow a little bit. We’re not going under the radar too often, but usually we don’t have as many DI (college) people as the teams we play. We try to make sure (our athletes learn) that hard work, dedication, positive attitude and don’t ever give up, fight through your adversities and just keep going, keep going, keep going.
“I get letters from kids that went to boot camp that said, ‘Oh my gosh, the only way I survived this is because of our practices and our tryouts. All these other kids are stopping, and I keep going.’ … Other ones go on to be doctors and nurses in the field. That’s what it’s all about, when kids are fighting through stuff. If they have all-nighters, they can figure that out and they know they have that inner strength they haven’t tapped into yet, that willingness to keep going. I think that’s what high school sports are about – teaching them the skills they need in life, to fight through things, that you’re capable of more, you just have to sometimes dig deep, shake it off and step it on up. … It’s just kind of a thing that sticks with some of these kids, and when you see them or get invited to weddings or whatever, it has nothing to do with records or scoreboards. It’s continuing in their life, watching them have families and successes in careers – that’s when it’s fun.”
Ingalls has provided two decades of experiences on and off the court her Saints will never forget.
Through the end of this regular season, she has led the St. Ignace girls basketball varsity to a 464-80 record since taking over the program prior to the 1999 season. Her wins are the 18th-most among girls basketball coaches in MHSAA history, and she has led teams to five Finals championships and four runner-up finishes – or a championship game berth to conclude nearly half of those seasons as head coach. Her teams have reached at least the MHSAA Semifinals 11 times, and won 16 conference, 18 District and 14 Regional championships.
Ingalls also has served 20 years as a board member for the Basketball Coaches Association of Michigan (BCAM), including a three-year term as part of the executive board serving as president-elect, president and past president, and she continues to serve as chairperson of the Miss Basketball Award committee. She also has served on the MHSAA Basketball Committee.
“Dorene is someone who has been passionate for years about providing opportunities for young women,” MHSAA Executive Director Mark Uyl said. “That's easily seen in the work she's put in not just with her program but as a strong voice of leadership for the Basketball Coaches Association of Michigan. She's been one of the strongest advocates for girls basketball in our state over the last 20 years.”
There’s some necessary context behind all of those on-court win-loss numbers. St. Ignace has only about 200 students and generally plays in Division 3 (or formerly Class C) or Division 4 – yet during the regular season the Saints frequently line up games against much larger opponents from all over the state. They’ve had their share of stars, especially for such a small schools, but the success is also a testament to how Ingalls works to find specific roles for as many players as possible – whether it’s for a minute here or there to grab a rebound or get a steal, many play at least some little part in keeping the team moving forward.
And the memories made off the court have meant just as much, if not more.
Clement, who became the Upper Peninsula’s first Miss Basketball Award winner in 2003 and then a four-year captain at U-M, recalled how much she and her teammates laughed with their coach and how Ingalls has a talent for connecting with her players.
“Her record by itself could garner consideration for this award, but that is not the primary reason I write this letter,” wrote St. Ignace superintendent Don Gustafson in nominating Ingalls for the WISL Award. His daughter Linnie played for Ingalls four seasons before graduating in 2018.
“She teaches basketball, but she teaches much more than basketball. The characteristics that Dorene models for the athletes who have played under her tutelage are dedication, perseverance, teamwork and life lessons, to name a few. The players she has coached in the past stay connected with Dorene long after that graduate, as (she) continues to provide guidance and advice even after the student athlete’s playing days have concluded.”
Like many families, cancer has impacted the Ingalls – both she and her husband Doug lost their mothers to the disease when those women were only in their 50s. St. Ignace’s trips to East Lansing, or Grand Rapids to play at Calvin College, or last year to Detroit to play in the Motor City Roundball Classic, included trips to medical facilities.
At the cancer center in East Lansing, the Saints inadvertently crossed paths with a St. Ignace resident undergoing treatment, and Dorene still is brought to tears retelling how they connected with that patient and were able to give her tickets to come watch them play that weekend. The Grand Rapids center was where Ingalls went through rehabilitation after suffering paralysis during childbirth in 2005; she remains partially paralyzed and uses a wheelchair.
Last season, before COVID-19 grounded the Saints’ chances to win another title, the team visited Karmanos Cancer Center in Detroit, including the room where one of the player’s mothers had fought for her life just a year before. That mother was part of the visit and, as Ingalls recalled, “to have that, and not the state championship, that’s probably more important. … That was pretty special. They’re learning the lessons that you’re hoping they do.”
This season’s team hasn’t enjoyed the “changing life” speeches that are part of usual bus trips, because right now the Saints aren’t taking buses to away games. But the pandemic has provided other opportunities – like when the team did workouts in the snow before full-contact practice was allowed to resume, or spent one practice performing skits for each other from the 1970s and 80s just to “break up the uncertainty and negativity.” Ingalls called it making the most of what you’ve got – and those are the memories she knows won’t be forgotten.
There has been recognition. She was inducted into the Upper Peninsula Sports Hall of Fame in 2016 and received the Michigan Sports Hall of Fame’s Treasure Award in 2017 – in addition to various Coach of the Year awards both for the Upper Peninsula and statewide over the years. She was named the Prep Person of the Year by the Detroit Free Press in 2011 and received BCAM's Tom Hursey Distinguished Service Award in 2018.
All are proud moments. But perhaps the proudest is another effort that keeps on building. Mining a connection to Lowell High School and its Pink Arrow cancer awareness games – St. Ignace alum Nate Fowler is Lowell’s superintendent – Ingalls hatched the annual Hooping for a Cure basketball game in 2009. Cedarville, Cheboygan and Mackinaw City have joined in the fundraising game since, and the event became a doubleheader this season with the girls and boys teams both playing.
The event raised a record $35,000+ in 2020, and more than $25,000 this season despite attendance restrictions. That brought the total to more than $245,000 – funds that at first were donated to the oncology department at Mackinac Straits Hospital in part for the purchase of specialized examining tables and chemotherapy treatment infusion recliners. Once the equipment needs were met and a new hospital – Mackinac Straits Health System – was built, the money went into a No Cancer Patient Left Behind fund that provides financial support for patients who have to travel outside of the area for further treatment.
“This benefit game and ensuing experiences for the team have taught us about being grateful for every day we do have and to have the courage to fight through adversity,” Ingalls said. “These vital lessons will carry on in all of us for a lifetime.
“In fact I recently received a photo from a former player sitting in one of the infusion chairs getting treatment for an autoimmune disease that really struck me deeply. Talk about full circle.”
Ingalls is a 1986 graduate of New Baltimore Anchor Bay High School, where she played basketball, volleyball and softball. She attended Lake Superior State University, earning a bachelor’s degree in geology in 1991, and she then moved to St. Ignace to begin six years as a geologist before starting a screen printing and embroidery business.
She had earned 10 letters playing four sports at LSSU – volleyball, basketball, softball and tennis – and soon after moving to St. Ignace she joined the Saints’ coaching ranks, first as a junior high and assistant junior varsity basketball coach in 1992-93, then junior varsity girls head coach from 1994-98 until she took over the varsity position. She also has coached softball and subvarsity boys basketball.
Ingalls and husband Doug have two sons, Jackson and Jonathan.
The first Women In Sports Leadership Award was presented in 1990.
