TPV
Methodology

What TPV Is

TPV (Total Player Value) is a single 0–100 rating that combines a player's offensive production, defensive activity, and overall impact into one comparable number. A score of 50 is exactly league average. Each 10 points is roughly one standard deviation — so a 70 means a player is two standard deviations better than the average qualifier, which historically corresponds to All-WNBA-level seasons.

How It's Calculated

1. Qualify the pool. Players need 300+ total minutes and 10+ games. Small samples produce noisy rates, so they sit out until the body of work is real.
2. Z-score normalize 13 component statsacross the qualifying pool — every stat is converted to "how many standard deviations above or below the average qualifier."
3. Weight and combine into offensive (40%), defensive (22%), and composite (38%) buckets — weights below.
4. Scale to 0–100: score = 50 + (combined z-score × 10), with a small minutes-confidence bonus for heavy-minute players whose rates are most trustworthy.

Validation

The model is calibrated against 2025 All-WNBA selections — the players the league itself identified as its best. TPV v2.0 placed all ten 2025 All-WNBA selections inside its top fifteen, with the MVP at #1. We re-validate every season and publish changes when weights move.

Derived Metrics

• Cap Value Score = TPV ÷ salary in millions. A player producing a 60 TPV on a $400K deal scores 150 (Elite value); the same production at $1.4M scores 43 (Below market). Powers the Cap Value tracker.
• In-season updates: during the season, players who cross the 300-minute / 10-game threshold get their TPV recalculated on current-season data; everyone else carries their most recent full-season rating until they qualify.
