True Shooting Percentage is the gold standard for single-number scoring efficiency. It incorporates all three forms of scoring (two-point field goals, three-point field goals, and free throws) into a single unified efficiency rate, expressing them as points scored per shot attempt (including free throw sequences).
Pace-neutral. Accounts for all scoring sources equally. Era-comparable (z-score normalization handles era differences). Available back to 1946. The analytics community broadly treats TS% as the single best measure of offensive efficiency for a scorer.
Raw TS% does not adjust for shot difficulty. A player who takes only open corner threes and dunks will have a higher TS% than one who creates difficult pull-up jumpers — but the latter may be more valuable if they're creating high-quality shots for themselves and others. TS+ (used in APEX alongside TS%) addresses this.
TS% is scored in APEX's Scoring Efficiency pillar alongside TS+, FTA/FGA, and USG%. It is the primary efficiency anchor of the Scoring pillar. The analytics community near-universally treats TS% as the baseline for scoring evaluation. APEX also uses TS+ to supplement TS% with shot-quality adjustment.
