Softball week 9 rpi - April 30

Does opponent's opponent come into play with RPI?

RPI consists of your record [25%], your opponents' record [50%] and your opponents' opponents' record [25%]. There are bonuses rewarded for "good" wins and penalties for "bad" losses, which when applied to your RPI gives your "adjusted RPI", a decimal value to 5 or more places. These decimal values are the actual RPI, but what people generally call "RPI" is the ordinal rank of your team's RPI. Louisiana's RPI yesterday was .66523, which ranked 10th, so everyone says our RPI is 10. Today's numbers have not been released yet, but the rankings have. The Cajuns are still 10th.

So, even when not every team plays Louisiana directly, there is still a round robin juice boost from the ones who do play Louisiana.

Sure, but that doesn't help as much as you would think. If Marshall plays 50 games and each of their opponents plays 50, each game that Marshall played against Coastal, would create a Louisiana component in Marshall's RPI of our winning percentage, say .75000 divided by 2500, then multiplied by .25, or .000075 for each game Coastal played us. Helpful, but not earthshattering.

In Marshall's case, Coastal playing Marshall helped us more than it helped Marshall.

Got it. Thanks.
