Practical Basketball Shot Release Timing Analyzer

Compute make probability and release window per shot type in Practical Basketball. Inputs in milliseconds, ratings 0-99, contest in meters.

Score a Practical Basketball shot attempt for make probability, release band, and contest impact.

Make probability: 92.1%
Release band: optimal
Optimal release (ms): 650
Effective tolerance (ms): 110
Contest penalty (0-1): 0
Confidence: 99.0%

Why a release timing analyzer?

Practical Basketball uses a release-window shot-timing system (no percentages, pure skill). The Shot Release Timing Analyzer is a deterministic scorer you can run in your browser. It does not invent data: every score is computed from the timing offset, the shot type’s optimal release, the contest penalty, the shooter’s ratings, and a confidence gate.

Inputs

  • shot_type — one of jump_shot, layup, floater, fadeaway, off_dribble, hesi_pull, moving_shot, standing_dunk, driving_dunk.
  • hold_ms — how long the shoot button was depressed (0-1500).
  • release_offset_from_optimal_ms — signed deviation from the optimal release (-300 to +300).
  • defender_distance_m and defender_height_in — contest geometry.
  • shooter_height_in — affects dunk sigma height bonus.
  • Shooter ratings — three_pt, midrange, standing_dunk, driving_dunk (0-99).
  • is_contested, is_mobile_input, stamina_low — modifiers.

Outputs

  • make_probability in [0.02, 0.97].
  • release_band — early / optimal / late / miss_zone / insufficient_data.
  • optimal_release_ms — the optimal release for the selected shot type.
  • sigma_eff_ms — the effective tolerance after contest + height + mobile adjustments.
  • penalty_step in [0, 1].
  • confidence in [0.30, 0.99] — degrades when inputs saturate.

How to use the analyzer

  1. Run 50 stationary jump-shot reps with is_contested = false and is_mobile_input = false. Aim for make_probability ≥ 0.60 and release_band = optimal on every attempt.
  2. Add a defender at 1.5 m with is_contested = true. The probability should drop by ~10-15%.
  3. Repeat with a tall defender (84 in) at 0.5 m. The probability should drop by ~25-30%.
  4. Use the release_band to coach yourself: late releases should pump-fake and reset; early releases should pull up.

Edge cases

  • hold_ms clipped to 1500 → confidence reduced.
  • Defender overlapping the shooter → penalty_step = 1.0.
  • Mobile input → +15% sigma.
  • Dunk height bonus → +10% sigma per 12 inches above 78 in (dunks only).
  • Pumpfakes are distinguished by tap-vs-hold; pumpfakes bypass the engine.
