If you aren’t looking here… https://stats.ncaa.org/selection_rankings/nitty_gritties/ then you aren’t looking at “THE” RPI. There are others who have pretty accurately reverse-engineered the algorithm, including d1softball.com, but I have seen close miscalculations at most of them. The benefit to using non-authoritative sites is that you get real time predictions. The downside is that you might be looking at a false report. The NCAA typically only updates once per day, usually by 9 or 10 in the morning. Just make sure you include games through yesterday’s date. If you don’t see yesterday’s date, refresh the page. If you still don’t see yesterday’s date, they haven’t published the updated calculation yet ** Edited by Mike_Louko at 5/9/2026, 8:47:37 PM
