Low Confidence
10 / 17 matches for full confidence· Last recorded match: 8/26/2026

Only 10 of the 17 matches needed for full confidence in the 2026 window. The rating is pulled toward the league average, so the handicap may shift noticeably as more results arrive.

The line re-checks the handicap after every match — from results, winning and losing margins, the strength of who was played, and home or away. Each dot is the number that applied going into the next game.

Formula: Rating = 1000 + (weighted score × 500). Each factor is normalized to −1…+1, multiplied by its weight, then summed. Window: factors are computed from the Handicap Calculation Years only (2026), excluding walkovers — the same window the official recalculation uses. Bayesian shrinkage: the raw rating is pulled toward 1000 by confidence (window matches ÷ 17, an adaptive threshold set by the last recalculation). Offsets: division and B/C/D team offsets are then applied, weighted by where each window match was played. Recency blend: the calculation years are re-weighted at up to 40% by match volume. Players with a long career but fewer than 5 window matches fall back to their full career record. Rating maps to handicap 0–15 (lower = stronger) via the league's spread multiplier.
