F5 (first-5) totals — forward learning

The F5-total models retrain every day on every game that has gone final (they learn forward). This is their live, accumulating record: each model’s daily prediction logged and then graded against the real first-5 score. The honest measure here is accuracy (how close to the actual total) — gradeable on every game — not “beating the line,” because F5 lines are thin and ~99% static. A vs-line win/loss is shown only as a bonus where a real F5 line existed. Question this answers over time: does learning daily make them more accurate — or sharper than the market?

NO BETS. Research. The backtest is unverifiable (frozen lines) and the rule-selective version failed (2026 = 49%). This page is the forward proof-or-bust. Believe nothing in the vs-line column until a large N clears the 52.4% break-even.

RMSE/MAE in runs. The market’s own implied number lands ~3.0 RMSE on F5 totals — matching that means we’re as sharp as the line; beating it forward is the bar.
