I know my conference is weak this season, but I'm getting tired of losing ground in the RPI when beating teams even if there really bad. I should at least stay the same or move up 1 or 2 spots for winning, when I should be winning.



They should make it even, when I lose to a top 50 RPI team. I should stay or move up for just playing that team. Instead I lose ground when losing to those team and when winning, (when I'm suppose to win) against bad RPI teams. This is rediculous.

you know rpi is a forumla that WIS did not invent, right? if you were talking about rankings, maybe you would have an argument, but rpi, sorry, thats just how it works.

Its a sad situation when furry is the smart one in the family.

Yeah, its just math. 0.25 * your win pct + 0.5 * opp win pct + 0.25 * opp opp win pct = rpi.

He must not realize that his RPI is compared relative to everyone else's RPI's.

Don't forget that a home wins and road losses count as .8 and home losses and road wins count as 1.2

It is .6 for home wins/road losses and 1.4 for road wins and home losses

oh LOL that's a good one. I know how the formula is for the RPI, I'm just saying, I don't like it.

I don't like it that much either, but its simple. Take it up with the NCAA.

I don't like ERAs in baseball, either. Someone change it.

IMO, HD's version of RPI, even though based in reality, should be changed. It gives double the amount of weight to what opponents do versus if a team actually wins or not. The math, in this case, is misguided. Now, it might be ok for RL use, where the selection committee uses it (at least this is what they ALWAYS say) only as a guide to differentiate teams that are ALREADY closely matched using OTHER criteria. In HD, it's a great deal more closely correlated to inclusion and seeding. So if HD is going to use such a formula, I think it should simply put more weight into actual win-loss percentage, relative to what opponents do. That is still important, but twice as important as actual win-loss percentage? I'm not buying it.

Btw, this is not a defense of the original poster, who seems to lack understanding of how RPI is going to continually adjust throughout the year, as previous opponents' win/loss percentages change dramatically, comletely independent of what the team does.

I'm with you jskenner.

I'm not good enough to play at D1 so maybe it works there. At D2 I don't think it does and for D3 I'm quite confident it does not.

Especially for D3, there is such a boost to playing on the road and such a small disadvantage with regards to home court that you regularly see quite a few of the "best" teams (according to RPI) play a slate of 10 non-conference road games. I've been guilty of that myself. And the overwhelming majority of challenges that I receive are so that I'll be the home team to give my opponent another road game.


Even for D2 when I get challenged for a game, there is probably a 80-85% chance it is going to be for me being the home team. Folks want to play on the road because it's going to help you for making the postseason as well as for seeding.

There are lots of good opponents that I'd like to play in non-conference that I "can't" because neither of us is willing to play on our own home court. For me, I want to have at least 5 road games and in all honesty I'd prefer 10. It's in my self-interest to play those 10 road games. At the same time I think it perversely affects the RPI way too much to be doing that.

And ignoring the perverse affects on RPI, it also is a disincentive for my enjoyment of the game. I'd much rather play a good coach at my place than some "nobody" coach on the road. But when you have a ton of folks playing 10 road games, you sort of feel like you have to keep up with them. I used to have a non-conference slate that I actually enjoyed as much, if not more, than my conference rivalries. Now, there is a game or two that piques my interest. And the majority of the others are games that I don't really care about but are scheduled to boost my RPI.

Like jskenner says, in real life it's a tool for the selection committee. Here it holds a lot more weight. In real life when the Missouri Valley tried to "cheat the system" with all their road games, you ended up with a team like Missouri State getting passed with a RPI of 21. In this game, there is zero chance that team misses the tourney.
