What does QRF stand for?
Quality Results Formula
What is the formula?
Every game gets an iQRF (individual QRF). If you play 20 Minnesota opponents*, you will earn an iQRF for each game. The QRF score you see online is an average of all those iQRF s.
If you win:
X = points for winning the game based on opponent Class.
Y = points based on opponent s opponents Class.
iQRF = X + (Y times opponent wins)
If you lose:
Y = points based on opponent s opponents Class.
iQRF = (Y / 3) times opponent wins
Why isn t the formula public?
Technically, it is public (see above). The part that isn t is what specific value is used for X and Y. These values vary from sport to sport and Class to Class in an ongoing effort to create a balance between the value of winning games, the value of playing tougher or weaker teams, and the competitive differences from Class to Class in each sport.
Not disclosing the values of X and Y was a joint decision between the MSHSL and Minnesota-Scores.net. The main reasons are so teams do not try and manipulate formula results (which is what happened in the past) by artificially scheduling teams that would earn them a lot of points. Which, by the way, is REALLY hard to do with the QRF. But not disclosing is a safeguard against that.
Also, some will think we give too many points for wins and some too few. Some will think we give too many points for losses, and some too few. Some will think we give too many or too few points for opponent s wins, etc. - eventually someone will find something to disagree with and make the results invalid in their mind.
The old adage of not wanting to know how a sausage is made comes into play here - we prefer to have the QRF judged on the end results and not the specific ingredients because there is no consensus on what ingredients should be used.
Is margin of victory/defeat included in the QRF?
The formula at the top is the entire formula, no mention of a score. It was part of the equation thru the spring of 2011, but was removed by request of the MSHSL in order to use the QRF for seeding.
If the QRF works so well, why do you need a Tiebreaker Margin?
Because using it for seeding makes seeding better, and helps put teams in a more logical order. In the end, all the QRF is, is a point value for how well a team has performed during the year. Very similar results provide very similar values, they do not create absolute differences. So if a team is ahead by .1 of a point, it does not mean they are better. It means they are similar.
Seeding teams needs to provide a narrow scope, usually comparing one team vs. another. So being able to apply what normal humans would as often as possible to make the seeds make sense, tends to be more fair.
How should I schedule my games if I don t know what value each opponent is worth?
This one comes in a lot. "Should I schedule a good AA team I know I m going to lose to or a bad A team I know I m going to beat”. The answer is easy, it does not matter. Your team is who they are and the QRF will find you either way – if you are a middle of the road team you are going to beat some good teams you shouldn t and lose to teams you shouldn t. Teams that play better teams and lose generally have about the same QRF as teams that play poorer teams and win. The QRF will find you either way you go.
In the end, 90% of the teams you beat will be below you and 90% of the teams you lose to will be above you. So if you want the best QRF possible, schedule the best possible teams you can beat.
Do I have to schedule a certain number of section opponents to be qualified to be ranked in the section QRF?
No. The QRF calculates based on all of your Minnesota* games played regardless of the opponent. There is a minimum number of Section games required in order to use Section Winning Percentage in the Tiebreaker Margin, but the formula itself could care less.
*How does the QRF handle games played against non-MN teams?
Two different answers. Because football has so few games, it was requested to include it in the calculation.
Football - games against a non-MN opponent count in the calculation. To do this we track up to the first 8 games (because most states play more than 8 regular season games) of every out of state team a MN team plays so we know how many wins they accumulate during the season. These out of state teams are also assigned to a "MN Class" so they can give equivalent point value to the size of their school.
All other sports - games against a non-MN opponent are ignored in the calculation. It isn t possible for us to track all of the opponents and all of their games. This may sound like a big deal, but it really isn t. Most other sports play between 16 and 26 games, so having 1 or 2 not count isn t statistically a big deal. Also, teams are not required to play the same number of games, so whether a team plays 23 MN and 3 non-MN or just plays 23 MN teams, the QRF treats them the same. Since the final QRF is an average and not cumulative, it all works.
As for the seeding, we do recognize these games were played and want to put some importance on playing them (otherwise they are just a scrimmage) so they ARE included if the Tiebreaker Margin is used for Overall Percentage.
How are forfeits handled?
Forfeits are ignored for all sports. The QRF (and seeding) is an attempt to apply on the field results into a point value and possibly a seed. Any game that is forfeited is ignored in the calculation AND in the Tiebreaker Margin for Overall/Section Percentages.
What order are the tiebreakers used when applying the Tiebreaker Margin?
- Head to Head
- Overall Winning Percentage (not inc. forfeits)
- Section Winning Percentage (not inc. forfeits) (min. 25% of games played)
- Coin Flip
When I "Submit a Score" it doesnt get immediately posted to the site....why?
We dont require people to log in as a specific representative for a team to submit scores, so we encourage ANYONE to send in the scores. The philosophy is, if you were at a game and can see the scoreboard (or listened to it on the radio), its not that hard to know what s what and send it in.
However, because we allow ANYONE to send in scores, we can t let everyone in the state have direct access to the database. So when you "Submit a Score", the email get sent into a pool of all scores submitted. It is received, verified for validity (don t submit a Football score of 176-3 for instance), then we will put it in the database to go live to the general public.
So why isnt it posted immediately? Because that Inbox isnt monitored 24/7/365. Its monitored more like 4 or 5 hours a day and generally during peak times for scores to come in.
Why do I have to give my name and email address when I "Submit a Score"?
So we can contact you if there is a conflicting score. That s it.
Your trust and confidentiality is important to us, so dont worry about us selling your email address. We hate SPAM as much as you do, so you have our guarantee that we will never release that information to anyone.....ever!
Why isnt there a QRF yet?
Usually because there isnt enough data to make it relevant. Its based completely on results, so the more results the better the rankings. You can expect the first QRF to show about 30% of the way through a particular season.
When in doubt, take a look at the top of the QRF Rankings page. It should have a date showing the first time it will be calculated.
How do you get your scores?
Basically the same way you do. But the advantage here is that we actively look for them instead of waiting for them to be reported. A HUGE part of that is your participation in reporting them accurately. And again, you dont need to be a coach or a school admin to know the score of the game!
