Today Brain may publish a number for 5 of 41 assets.

Brain's number is a win rate measured over calls that have closed and been scored on live data, not something a model generated. Below 30 live samples that number carries no statistical meaning, so the system publishes none at all. 5 of 41 assets currently clear the bar.

A backtest runs over data whose outcome is already known, so it measures fit to the past rather than accuracy about the future. After incident ADI-478 — where blended counting let a 100% backtest win rate through as if calibrated on live data — the gate counts live samples only.

At the sample sizes available, a win rate's 95% confidence interval spans tens of percentage points, so a single number would pretend to more precision than exists. 30 is the threshold for being allowed to speak, not a threshold for being sure: narrowing the interval to ±5 points takes roughly 385 samples.

No. Every number on this page is public: no rate, interval or sample count appears only after signing in, and the same 30-live-sample rule applies to everyone. Signing in opens the conversation, the invalidation board for your own watchlist, and War Room — it does not unlock a single extra number.

Not better-looking numbers. Pro opens unlimited conversation and War Room Debate, where several independent voices argue and then revise the call's own invalidation line. Every rule on this page applies to paying users unchanged: below 30 live samples, War Room publishes no probability either.
