Matches a pattern that lost clearly more than the trading costs in the backtests.

Consensus side under 30¢Longshots (0.05–0.30) lost −29.5 % a trade pooled (n 1,625; −22 % in spring, −35 % in October): the strongest effect in the backtests.
Spread or totalSpreads and totals: −14.5 % a trade in spring (95 % CI −27 to −1), +1.5 % in October: no edge.
Consensus under 60 %Every backtest started at 60 %+ of the holders; below that nothing was measured.

Backtest of Oct 22 2026: one entry per market, held to resolution, after a 1¢ half-spread and Polymarket's taker fees. The grade never goes above “Research candidate”: no rule passed the multiple-testing check. It is not a forecast and not advice.
