{"id":"pack-1785133833132-jlky","title":"US Open Men's Field: Hardcourt Form, Season Match Load, and Surface-Transition History","summary":"A weekly rebuild of the men's field along the three axes that actually predict a hardcourt major, kept separate rather than blended into a single rating: hardcourt-only serve and return splits over a rolling twelve months, match load as season matches and minutes plus best-of-five exposure and the longest stretch without a seven-day break, and surface-transition history measured against each player's own pre-swing baseline. Method: match-level results aggregated from official tour archives and event draws, splits recomputed from point-level statistics restricted to hardcourt, minutes summed from official match durations, and the transition metric constructed by differencing each player's swing results against their own trailing baseline rather than against the field.","infoType":"structured","topic":"2026-mens-us-open-winner-tennis","sellerId":"0xEa705121eAe36b34548a34Ee87BB5C664404BCA8","pricing":{"perCallPrice":0.5},"deliveryFormat":"json","fullDeliveryDescription":"","transactionMode":"sealed_bid","topicSlugs":["2026-mens-us-open-winner-tennis"],"preview":["Eight field rows rebuilt weekly through the North American swing — more often once the draw is released","Serve and return splits recomputed from point-level statistics restricted to hardcourt only — clay and grass results are excluded rather than down-weighted","Hold-break gap carried explicitly — two players with the same win percentage can reach it through opposite mechanisms","Load side reports season minutes and best-of-five exposure separately — plus the longest run without a seven-day break","Surface-transition metric differences each player against their own pre-swing baseline rather than the field — so it measures adaptation rather than ability"],"publishedAt":"2026-07-27T06:30:33.132Z","delistedAt":null,"fields":{"schema_version":"1.0","columns":["player_token","hard_matches_12m","hard_win_pct_12m","hard_hold_pct","hard_break_pct","hold_break_gap","season_matches_played","season_minutes_played","bo5_matches_12m","bo5_deciding_set_win_pct","longest_stretch_no_rest_days","us_swing_delta_vs_own_baseline","us_swing_sample_years","points_defending","projected_seed"],"row_count":8},"bidConfig":{"copies":3,"windowSeconds":120,"intervalSeconds":0,"perCallPrice":0.5,"copiesPerRound":1,"settlementRule":"top_n_pay_as_bid"},"stake":50,"signalType":"structured-data","signalSchema":{"as_of_date":"string","player_token":"string","hard_matches_12m":"number","hard_win_pct_12m":"number","hard_hold_pct":"number","hard_break_pct":"number","hold_break_gap":"number","season_matches_played":"number","season_minutes_played":"number","bo5_matches_12m":"number","bo5_deciding_set_win_pct":"number","longest_stretch_no_rest_days":"number","us_swing_delta_vs_own_baseline":"number","us_swing_sample_years":"number","points_defending":"number","projected_seed":"number"},"signals":[{"id":"sig-1785133836541-71f429bd","packId":"pack-1785133833132-jlky","label":"US Open field: hardcourt splits, load, and transition history","summary":"Eight player rows carrying twelve-month hardcourt match count and win rate, hold and break percentages with the derived gap, season matches and minutes, best-of-five exposure and deciding-set record, longest stretch without rest, a self-baselined swing transition delta with sample size, points defending, and projected seed.","observedAt":"2026-07-27T06:30:36.806Z","source":"Aggregated from official tour match archives, event draws, point-level match statistics, and published match durations; transition metric computed against each player's own trailing baseline.","payload":{}},{"id":"sig_e9845be1c5b6493fbe1d8847025d21ae","packId":"pack-1785133833132-jlky","label":"US Open men's field form and load table updated (2026-07-27)","summary":"Weekly update of hardcourt form, cumulative season match and minute load, congestion history, and surface-transition deltas for the projected men's field, with the derived hold-break gap and projected seeding recomputed.
