Hawthorn Multi System · The Gate · Calibration Ledger · Est. R12 2026
Rule #1: the gate's job is to kill bets, not approve them. Some weeks the right output is "no bet".

📈 Calibration — do my claimed numbers survive contact with reality?

⚠ Standing note from R16: multiple "84–92%" anchors failed in one game (correlated team-level failure). Until the ledger proves otherwise, mentally discount anchor claims by ~5–10%.

🐎 Spring Racing · 29 Aug - 29 Nov 2026 · Hawthorn Rules, Carnival Edition

SEASON OPENS 29 AUG
Same objective as the footy system: have fun AND genuinely try to win. What the 5-spring backtest (2021-2025, 14,685 races) proved is that no autopilot formula wins here, so the shot at a winning season comes from the same place it does with the Hawks: picking a small number of spots you actually have a view on, pricing them yourself before looking hard at the market, and letting the gate kill the weak ones. Quality over quantity: 15-25 gated bets across the whole carnival beats 5 ungated bets every Saturday. One season budget set before Memsie Day, never topped up: that's the worst case, and finishing ahead of it is the win condition. Every bet logs a claimed win chance, and the calibration line grades your judgement at season's end, exactly like the footy leg ledger.

Season record

Settled fun-ledger bets; pending in brackets. Each-way = two entries.

🎟️ Fun Ledger · every bet, reason first

DateTrackSelectionMy %OddsStakeResultP&LWhy

🚪 The Racing Gate · every box ticks or the bet dies

G1 · A real view, not a vibe. You can say WHY this horse in one sentence grounded in something specific: form line, map/tempo, track or weather bias, class drop, jockey/trainer intent. "Nice name" and "everyone's on it" die here.
G2 · Your price first. Write your claimed win % BEFORE settling on the market price. Only back it if the market's odds beat your number with room to spare. If the market agrees with you, there's no bet: that's the SGM value-leg rule in racing clothes.
G3 · Singles on the exchange, best odds. Betfair or verifiably better fixed odds. Allowed shapes: win, place, each-way (log as a win + place pair), and dutching 2 runners in one race (log as two singles, same reason). No racing multis, ever: legs are independent, so a multi only compounds margin. The Backtest Lab is the proof.
G4 · Season budget is structural: $50, locked 31 Jul 2026. Mirrored as the Betfair deposit limit, never topped up. Stake rule, also locked: $5 each-way standard ($2.50 win + $2.50 place), one $10 A-grade allowed per meeting, target odds $6-$12. That's 8-12 quality bets for the season. The signature shape is the racing SGM: place half collects often, win half is the big one. Footy money and racing money never mix.
G5 · No chasing, no Cup-day impulses. A losing Saturday changes nothing about Sunday. Cup-day extras beyond the plan come from a small pre-set sweep budget, and the gate applies from bet zero.
G6 · Day rules: stop-win and stop-loss. Once the day is in front, it's banked: no more bets that meeting. Down 3 stakes: day over. Simulated on 1,921 real meetings this turns "leave positive 44% of days" into 75%, and caps the worst day at 3 stakes. It doesn't create edge, it shapes the season so the fun survives.

🗓️ Season plan · 29 Aug - 29 Nov · quality over quantity

Before Sat 29 Aug (Memsie Day): season budget locked in above and in the Betfair app's deposit limit. Structural, not willpower.
Sep: footy finals are still the main game. Racing = the big Saturdays only, 1-3 gated bets max. Early reads on track bias and in-form stables become Insight Bank entries.
Oct: the deep end: Turnbull, Caulfield Guineas, Caulfield Cup, Cox Plate. This is where doing the form on a target race midweek (like Thursday-night footy prep) pays.
Sat 31 Oct: Derby Day, Flemington.
Tue 3 Nov: Melbourne Cup: sweep + one fun bet from the pre-set Cup budget. The gated bets hunt the undercard, where form holds up.
Sun 29 Nov: season closes. Calibration review: did the claimed win %s match reality? That answer decides what spring 2027 looks like.

📋 Race-day prep sheet · what Claude pulls before you price a race

  1. Fields, weights, gear + past runs (incl. going of each past start) — Claude self-serves from Racing Australia FreeFields
  2. Sectionals + replays contextracing.com, self-served (all carnival tracks are VIC)
  3. Weather + radar for the trackBOM station feed, self-served (footy weather trick, racing edition)
  4. Official track rating + upgrades/downgrades — Racing Australia / Racing Victoria on the morning; a mid-morning downgrade is a re-price moment
  5. Day bias read for late races — what's winning races 1-3: on-pace or swoopers, inside or out. Claimed % gets set AFTER this, not before lunch
  6. Speed-map / wet-track tables screenshot — punters.com.au or racenet are policy-blocked for Claude; you open them, paste a screenshot (the CBA% move)
  7. The price — read Betfair last, after your own % is written down. Gate G2 lives or dies on this order
  8. Log what the day taught you — bias reads, stable patterns, track quirks go in the Hawthorn Insight Bank prefixed RACING: so they're all there by Cup week
