Backtest Lab is a model inspection surface, not the public tracked-results ledger. It is most useful for comparing parameter sets against the same stored fight, result and odds pool.
All model leans treat every usable directional lean as a one-unit strategy bet. Value/advantage modes add a market-difference requirement before a lean becomes a simulated bet.
Time Safe: On (strict) is the cleanest audit mode. Bout coverage is limited to the strict public-result pool: settled fights that FiteQuant has tracked or recovered with enough pre-fight prediction, result and odds evidence to treat them as public ledger candidates. Strict mode applies pre-fight as-of filtering and disables objective-derived inputs that cannot be calculated without strict leakage risk.
Time Safe: On (non-strict) uses the strict pool plus explicitly verified non-strict rows. These are settled canonical bouts with ProBoxingOdds-backed closing odds and post-official-model fighter timestamp evidence, but without the full public tracked-result status. This mode is designed for lab work: it keeps the time-safe boundary, while allowing approved objective-derived exceptions such as opponent-rating fields for targeted models or custom selections. Height/reach delta is treated as an objective matchup dimension because it is based on fighter profile measurements rather than the fight result.
Time Safe: Off is non-time-safe historical simulation. It can use the broader stored canonical fight and odds pool inside the selected window, including inputs that may reflect current or later-persisted fighter data. In this mode, opponent-rating-derived fields and height/reach delta are treated as normal objective inputs when the selected model uses them. It is useful for exploration, not as evidence of tracked pre-fight performance.
For serious model comparison, change one lens at a time: strategy, market bucket, confidence tier, time-safety mode, or objective history window. The useful signal is usually the pattern across runs, not one isolated ROI cell.
