The exact method behind the public sports records at altoraanalytics.com — football, tennis, darts, snooker, rugby and esports — written as a complete, beginner-friendly handbook.

Not a tipster PDF. This is the engineering: results + odds data done properly, an Elo rating engine from scratch, market probabilities, a gradient-boosted blend, honest out-of-sample validation, and a live pipeline that publishes before play and settles in public.

What's inside:

• Free, legitimate data sources for results and odds (and the two ingestion traps)

• A complete Elo implementation — adaptive K, home advantage, margin of victory

• Turning odds into true probabilities: vig removal, closing lines, CLV

• The two-feature blend that beat every fancy feature we tried — proven across five sports

• Calibration: log-loss, Brier, reliability tables, Platt scaling

• The honest gate: chronological splits, the two-halves rule, ablation, pre-registration

• Football: a Poisson goals engine pricing 1X2, O/U, BTTS and correct score from one matrix

• The betting chapter nobody else writes: why most edges fail, and how to test yours without fooling yourself

• The 10-trap table from our own build, a 10-step roadmap, and a glossary

Who it's for: anyone comfortable copying code. No stats or betting background assumed.

Honest expectations: educational, not betting advice, no profit promises.
