story
Jumps heavy-beating rebound. In discovery, the close-form rebound in handicaps holds at 1.232 on 1600 across both periods. Sub-cuts also hold: recent winners (1.336 on 669; 1.265 at 14/1 or shorter), first run after a win (1.253), changed going (1.261 on 917) and held-or-raised mark (1.307 and 1.423). Failed or killed: non-handicaps (0.877), the Flat replicate (1.021), excuse without close form (1.05), dropped mark (IRE 0.96) and same-conditions (one band carries it). The quick-return test is untested at 12 bets. The lift sits at mid and long prices, and the 3/1-or-shorter bands are below 1. The data window starts in Nov 2025, about one jumps season. Flat wide trip. The broad rule scores 1.204 on 1119 and the 7f+ cut at 14/1 or shorter 1.259 on 643 (GB 1.218). The big-field 7f+ cut (1.352 on 227) and the no-story 7f+ cut (1.198 on 462) are frozen but overlap. At all trips and 14/1 or shorter, the no-story complement is weak (1.089, GB 1.011). The 10f+ and turf-only mechanisms were killed on period splits, and the big-field story sharpen is underpowered (75 bets). IRE runs higher throughout. None of the frozen rules has forward bets yet.

holdsAmong close-form jumps handicappers beaten 20+ lengths, an exactly unchanged mark scores 1.444 on 392 (p 0.007), a raised mark 0.762 on 114 and a 1 to 3 lb drop 1.185 on 941. The handicapper holding the mark is the ingredient, not improvement or relief.

holdsThe recent-winner heavy-beating rebound survives a 14/1 price cap: 1.265 on 447, with GB 1.247 and IRE 1.339. It is not just a longshot artefact, though the CI lower bound is 0.99.
