CEVO Performance Index (CPI) Explained

 

CEVO Performance Index Explained

 

We've been getting quite a few questions about the CPI in the last couple of weeks, so I've dug up an old news announcement that explains the system in detail.

 

CEVO has developed and released the CEVO Performance Index (CPI), a mathematical formula for calculating teams’ overall performance during the regular season. CPI is carefully constructed to take into consideration all the important factors for seeding teams in the fairest, most unbiased way possible.

 

CPI is calculated using six components:


1) Point Index

2) Win Percentage

3) Strength of Schedule

4) Margin of Victory

5) Opponents’ Strength of Schedule

6) Head-to-Head Modifier

 

Point Index is calculated based primarily on the number of wins. Forfeit wins grant teams partial points, as do overtime losses.

 

Win Percentage is a straightforward calculation of a team’s wins versus losses.

 

Strength of Schedule is determined by averaging the Win Percentage of each of a given team’s opponents, minus the match between that team and that opponent.

 

Margin of Victory adjusts the value of a given win depending on the difference between rounds won and rounds lost.

 

Opponents’ Strength of Schedule is determined by averaging the Strength of Schedule for each of a given team’s opponents.

 

Head-to-Head Modifier takes head-to-head match-ups into consideration by providing a small bonus for beating higher ranked teams and applying a small deduction for losing to lower ranked teams.

 

If you have any questions about the CPI, feel free to post them below and we'll do our best to address them in a timely fashion.  Keep in mind that some of these components become more accurate as more matches are completed.  So by the end of the season, CPI will be at its most accurate.

 

Thanks,

CEVO|Pipher

[quote="MrSoker"]What wizard came up with this? It's way overthought to a point where it doesnt actually depict the top teams [/quote] We had some bugs with the CPI that was causing the standings to appear out of whack. We've taken care of these bugs now. I think that you'll find when all the matches have been reported at the end of the season, and the CPI is at its most accurate, it will certainly depict the top teams. Thanks, CEVO|Pipher

Least rounds allowed, undefeated 5-0?.. Explain to why we are not #1 in the standings? Not sounding cocky but still do not understand this CPI..

(think college power rankings)

This is actually a very good system that matches teams up with other teams with very similar skill level.

Sorry but this system isn't fair at all. Basically if you go 8 - 0 and play crappy teams the whole season, then you won't get 1st place. It should be ranked by win loss percentage and the amount of rounds that you won by. The schedule should have nothing to do with it. There are teams 4-3 that are top 20 atm but my team who is 5-2 is ranked 40th. It's just not logical.

Teams that have similar CPI are matched up to play each other. So if you do go 8-0 you'll be up there. The system works well the way it is.

So our team went 6-2 and we lose out on playoff spots to multiple 4-4 teams. Seems legit.

Margin of victory doesn't make sense. Do you get more points if you have a bigger margin of round wins over losses, or if they are closer together? It would be kind of weird to get less points for a 16-0 then a 16-14

As if this kind of scoring system did anything when they tried it for CAL. Learn from other leagues mistakes.

Simply Illogical is ranked #1 with a worse margin of victory, that being 16-14, than all the other winning teams. WOTM8

CPI is looking to be a horrible system. I've never seen a ranking system that rewards teams for almost losing. Just because a team won 16-14 doesn't mean it was a good match. It could be both teams are just bad and it kept going back and forth. This system encourages teams to lose rounds because if they do they will be ranked higher. You guys say ease of schedule is a factor but how can you penalize a team for something we can't control like our schedule. Just because a team wins 16-3 doesn't mean the team they beat are bad maybe the other team is just better? CPI= lose as many rounds as you can without losing and you'll be in 1st place. Good luck to all

Why do teams with a total score of for exaple 450 - 0 have a worse CPI than Teams with an overall score of like 250-100 ? Because their Opponent was better? I cant understand this logic.

CPI is a pretty ridiculous metric -- the problem is if you win 16-0 you will be really high on the round differential portion but because you thoroughly crushed your opponents your perceived strength of schedule will be really weak so your CPI will be too low. Pretty lol that my team won 16-13 and 16-14 and we're considered top open by CPI...? I know there are teams out there 16-0ing open kids who deserve main but have lower CPI than we do, and it doesn't make sense at all.
