Every SportMath model, back-tested in the open: how good the probabilities actually are, not just how confident they sound.
Strict train/test split: each model is fit only on data from before the test period, then scored on matches it has never seen. No look-ahead.
Every model on this site is back-tested the same way: fit it only on data from before a test period, freeze it, then score its predictions against what actually happened. Nothing here has seen the results it's being graded on.
SportMath is free, open and runs entirely in your browser. If it made the games a little more fun, you can chip in to keep it running and growing. Any amount is hugely appreciated!
