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.

Jokela Caps LL-H Career As 3-Sport Star, Among Track's Most Accomplished Greats

ESCANABA — It would nearly be an understatement to say Emily Jokela has enjoyed a stellar high school athletic career.
The recent Lake Linden-Hubbell graduate earned a dozen victories at the Upper Peninsula Division 3 Track & Field Finals during her prep career, winning the 400-meter dash and 300 hurdles four times apiece, taking the 100 dash three times, adding a 200 title as a sophomore and 100 hurdles championship this spring.
Jokela also owns the all-time U.P. Finals record in the 300s at 44.8 seconds and the UPD3 record in the 400 (58.61) set a year ago – with school records in those events as well.
“I started running in fifth grade and fell in love with hurdling,” she said. “All my events were close together. I do weight training four times a week and sometimes go to the Michigan Tech track to get a break from our asphalt surface. The asphalt track is harder on the legs. It’s nice to get on a rubberized track.”
She concluded her prep basketball career here June 12 by leading the West All-Stars past the East, 50-41, at the 39th Annual Upper Peninsula All-Star Basketball Game.
Jokela, who scored 18 points in her final prep hoops appearance at Bay College, was selected Most Valuable Player. She finished her Lake Linden-Hubbell basketball career with a school-record 2,010 points, leading the Lakes through a 17-7 season this winter and earning an all-U.P. Division 4 first-team honor.
Jokela did double-duty this spring, also as a pitcher in softball. Lake Linden-Hubbell went undefeated in the Copper Mountain Conference (10-0) and finished 28-7 overall after dropping a 2-0 decision to Gogebic (Bessemer/Wakefield-Marenisco’s cooperative team) in their Division 4 Regional Final.
“I started playing basketball and softball at a young age,” she said. “I made some of my best friends in basketball. I’m going to miss all the girls I played with for four years. I’m so proud of how far we went in softball. I’m also very happy with how basketball went and quite happy with the way our track & field season went.”
LL-H brought home the Division 3 runner-up trophy from the U.P. Track & Field Finals at Kingsford by scoring 76 points, just eight fewer than Newberry. The Lakes were crowned U.P. champions last season and shared the title with Stephenson in 2023. Jokela was four-time all-state selection and three-time CMC MVP, and scored more than 1,000 points during her career. As a junior she won the 100, 200, 400 and 300 hurdles at the UPD3 championship meet and remains one of only seven girls to win four individuals events at a Finals.
On the basketball court, she was a two-time conference MVP and four-time member of the CMC’s elite team, and selected twice to The Associated Press, Basketball Coaches Association and Detroit Free Press all-state teams. In softball, Jokela was a two-time conference MVP and named CMC Pitcher of the Year.
Jokela earned another high honor in late May, being named her school’s Outstanding Female Athlete. She is bound for Grand Valley State University, where she’ll become a member of the women’s track & field team.
“I met my roommates, and they seem nice,” Jokela said. “It will be a lot more intense in college. I’m really going to have to work hard for everything. I need to work on my endurance. It was a challenge balancing track with softball, but I like being busy.”
Jokela also was a two-time all-state academic selection and a National Honor Society member. After carrying a 3.79 grade point average in high school, she plans to major in health science at Grand Valley.
