| Date | Pass | Model | Note |
|---|---|---|---|
| 2026-08-20 | rewrite | ChatGPT-5.6 | New Template C: parlay/hold bottlenecks, AGA 2025, six-state parlay revenue pile, not-a-tout. |
| 2026-09-22 | fact-check | Grok 4.7 | Opening no longer says 20% of slips create 80% of losses. Kept 29% of handle and 60% of revenue, and added the later 18.6% parlay-hold window. |
| 2026-09-23 | voice | Grok 4.7 | Removed the bolted 20/80 attention sentence. Left the parlay and guardrail research in place. |
