ESF / EFF — the Hybrid Intelligence engine.
ESF (Excel Soccer Filter) and EFF (Excel Football Filter) are one engine — nomenclature varies by audience. “Soccer” and “Football” are interchangeable in design; “football” persists as the stable term.
Why this engine exists
Raw fixtures are infinitely noisy. The bot eliminates entire classes of unreliable fixtures before any further analysis, then applies structure-based filters. What survives is signal. What is published is what survived.
Explicit exclusions (by design)
| Excluded | Reason |
|---|---|
| Knockout fixtures (e.g. UEFA CHL playoff) | extra time / penalties distort Full-Time settlement (1X2/DC only) |
| International friendlies | experimental squads; unrepresentative formations |
| Amateur / youth tournaments (e.g. WACC, Srikandi Merdeka) | insufficient data integrity |
| Zero standings (season-opening situations) | no competitive context yet |
| Dual-table leagues (e.g. Argentina Primera C) | confused hierarchy → H2H fallback with reduced rating |
| No-H2H histories | insufficient pattern base — the bot simply never lists them |
| Suspicious league patterns | match-fixing indicators are a first-order flag |
Educational environment: learn these markets in our Academy — including why we serve only 1X2 (the #1 global market) and Double Chance (top 5), and how the ODds of O/U, BTTS, corners etc are structured. We deliberately do not serve them.
Filter stack (what survives)
| Filter | Meaning |
|---|---|
| home_leads | home team ahead on standings |
| same_standings | equal points — parity fixture |
| played_parity | equal games played (fixture-load equal) |
| h2h_over5 / h2h_under5 | history depth control |
| large_gap | ≥9 pts separated — confident but value-compressed flag |
| SB (SureBet) rank | our internal confidence rank — not a guarantee |
| past_h2h_result | Elite: include last meeting outcome |
Data format contract
Every JSON carries: metadata.timezone: GMT+3, gender field (default men; women’s fixtures flagged — Pro/Elite toggle), and a full match object per fixture. Sample files at Today’s Data.
