The NBA, NFL, and NHL winner estimates use recent completed games, weighted scoring margins and a modest home advantage. The soccer model uses recent goals scored and conceded to estimate goal rates, then computes home/draw/away outcomes with a Poisson model. Soccer shot estimates use recent team shots and opponents' conceded shots; if sample data is thin, the model refuses to output a percentage.

Samples are limited to games before the selected matchup, so future games do not leak into a retrospective projection. Matchup strength, injuries, starting goalies, lineups, travel, weather, and bookmaker market adjustments are not fully modeled. Probabilities have not been validated out of sample. Never treat high displayed numbers as a reason to bet or chase losses.
