Proof of Record
Public calibration & realized edge
Betnix publishes its own report card. Every action the recommender surfaces is logged as a policy action; once the game settles, we compute realized return, closing-line value, and per-bucket calibration. Below is the rolling aggregate — no cherry-picking, no user data.
Proof-of-record is temporarily unavailable. Please check back shortly.
Brier — mean squared error between the fair probability and realized outcome (lower is better).
ECE — expected calibration error, 10 equal-width bins.
Avg CLV — average closing-line value in percentage points vs. the closing fair probability.
ROI — realized return on 1-unit bets, in percent.
