| health_penalty |
Penalizes horses when the latest race incident report or incident tags show health issues such as 健康問題. Higher value means bigger risk penalty. |
| consistency5 |
Rewards consistent recent placings across the latest races. |
| form3 |
Rewards strong recent form, with extra emphasis on the latest few runs. |
| rest_balance |
Rewards healthier rest spacing; avoids too short or too long layoff patterns. |
| besttrack |
Rewards fit between horse profile and track or distance conditions. |
| track_pick |
Rewards the track-level pick signal if the horse is selected by that source. |
| seq_top4 |
Rewards horses that appear in sequence-based top pick snapshots (seq 1 to 4), and adds extra score when current-race track2 is below 100; lower track2 gives higher additional score. Also applies an overlay boost to a high score when the horse has past quinella history (rank 1 or 2 in past6) but current opening odds (oddsfrom) are above 20. |
| marked_runner |
Rewards horses explicitly marked as runners of interest by source signals. |
| last_race_odds_drop50 |
Rewards horses whose last-race opening odds (lastoddsfrom) shortened versus last-race closing odds (lastodds), then adds extra retry credit when past6_0 is above 3, with rank 4 getting the strongest bonus and higher ranks tapering down. |
| lastload_drop_significance |
Standalone load-drop rule: rewards horses whose lastload is above current loading, with a non-linear bonus so larger load drops matter disproportionately more than smaller ones. |
| new_horse_improving_lastpace |
Rewards relatively new horses with fewer than 10 races when the last pace position improves from lastpace_0 to lastpace_1, with larger improvements scored disproportionately higher, extra credit when lastpace_0 is already near ranks 1 to 3, and an additional bonus when the horse has never run the current location+track+distance before. |
| odds_rebound_after_bad_last |
Scores higher when last race had strong odds shortening and current race continues to shorten, with past6_0 > 5 as the bad-last-result rebound condition. |
| low_last_odds_signal_bad_finish |
Triggers when lastodds is below 10, with lastoddsfrom - lastodds > 0, and the horse did not finish top 3 in the last run (past6_0 >= 4). Within that bad-finish range, better rank (lower past6_0) gets higher score. |
| top3_high_open_odds_penalty |
Penalty rule: deducts score when last run was top 3 (past6_0 < 4), but current opening odds are high (oddsfrom > 20) and opening odds are higher than last race final odds (oddsfrom > lastodds). |
| contrary_hot_place_after_bad_lasttime |
Contrarian market signal: rewards horses with weaker previous race outcome (higher past6_0) and slower lasttime versus besttime, but currently hot (lower) place odds, indicating strong market confidence despite poor recent form/time. |
| contrary_strong_odds_after_poor_recent |
Contrarian rebound rule: requires very poor recent profile (past6_0 > 9 and all past6_0..past6_5 > 6), then rewards when current win/place odds still show unusual strength either in absolute terms (relatively low odds) or relative to peers in the same race with similar latest rank. |
| rebound_quin_candidate |
Rewards horses with top-2 history whose latest run rank worsened versus prior run, while opening odds (oddsfrom) are shorter than last race odds (lastodds), indicating rebound market support. |
| besttrack_lower_better |
Rewards horses with lower besttrack value (smaller is better). |
| top2_history_bad_last_low_open_odds |
Rewards horses with historical top-2 pattern, weak last finish, and low opening odds profile. |
| recent_top2_rate |
Rewards stronger recent top-2 hit rate patterns. |
| recent_top3_rate |
Rewards stronger recent top-3 hit rate patterns. |
| seq_fresh_state_rank |
Ranks horses higher when they are still fresh (numRaces < 6), have better seq values (lower seq is stronger), and are marked with state + for improving form. |
| state_plus_rate_change_odds_track2 |
High-conviction contrarian rule: boosts horses when state is +, rate_change is at least 7, odds moved in a favorable direction across the last-race and current-race odds, the horse is still fresh (past6_0 < 4, seq < 4), current opening odds are below 6, SW is above 5, and track2 is below 100; lower track2 gives a stronger score. |
| low_odds_past6_quin |
Boosts horses when current opening odds are below 10, the latest past6 rank is poor (>= 10), and the recent past6 history includes a quinella position. |
| overlay_lastodds_track123_quin_potential |
Overlay potential signal: requires both lastoddsfrom and lastodds below 5, seq below 5, at least one of track1/track2/track3 below 100, and a past6 quinella record (rank 1 or 2). Lower qualifying track values and stronger prior quin history increase the score. |
| new_horse_trainer_season_win |
Overlay boost for new-horse candidates when the trainer has a winning record with new horses in the current season and the horse opening odds are below 20. |
| rate_change_gt6_same_class |
Rewards horses when rate_change is greater than 6 and the current race class matches the last class. |
| quin_ref_rating_loading_match |
Rewards horses whose current rating and loading are closer to the horse's recent historical quinella (rank 1 or 2) reference values. Adds a heavy-runner caution discount when numRaces > 20, current loading is more than 15 above lastload, latest rank is top 3, and market confidence weakens (oddsfrom > 10 and lastodds < oddsfrom). |
| best_stall_history_match |
Scores highest when current stall equals the horse's best historical stall under the same rloc, rdistance, and rtrack; nearby stalls receive partial score. Applies a discount when the current stall has historically poor outcomes under the same context, and adds directional stall-change effect: bonus when moving from weaker stall context to better stall context, penalty for the reverse. |
| sw_gt5_higher_better |
Rewards horses only when SW is above 5, and gives higher score as SW increases. |
| combo_best_pick |
Meta rule bonus: triggers when seq_top4, besttime_lasttime_speed, sw_gt5_higher_better, and rate_change_gt6_same_class all pass their combo thresholds for the same horse. |
| jockey_special_pick |
Uses jockey special-pick strength (yellow/red style from jockey switch patterns), then adds bonus when the new jockey has past quinella pairing with this horse or has higher ranking than the previous jockey. Impact is dampened when the last-race jockey (jockeyfrom) also has other special-pick targets in the same race. |
| grid_color_highlight_balance |
Scores by per-horse screen grid color counts: more red/yellow highlights increase score, while grey highlights reduce score. |
| besttime_lasttime_speed |
Rewards horses with faster besttime and lasttime values (lower times score higher), but applies a stale-besttime discount when numRaces > 20, especially when historical besttime is much stronger than recent lasttime. |
| rating_momentum |
Rewards positive movement in rating trend (upward momentum). |
| market_support |
Rewards favorable market support characteristics from odds-related signals (current and last-race odds shortening), but dampens the score when current odds are above 20; if past6_0 is in upper six (1-6) while odds stay above 20, score is reduced further. Also applies a strong penalty when lastodds was below 10 but current oddsfrom moves above 10 while the latest rank is top 3, indicating weaker current confidence. |
| stability_recent |
Rewards recent performance stability and penalizes volatile form swings. |
