All sports, nearest first. Tennis is filtered to matches involving a top-100 ATP/WTA player.
Pick a favourite and underdog, and the handicap line you're considering (e.g. -10.5 means the favourite must win by more than 10.5).
Pick a favourite and underdog, and the run-line you're considering (e.g. -2.5).
"Line" here works as a set-margin handicap on sets won — use -1.5 for "favourite wins in straight sets" style checks, or 0 for a plain win/loss check.
Every matchup check you save gets logged here, then resolved automatically once the game finishes. This is the number that actually tells you whether the model's percentages mean anything — not win rate, calibration.
