What's Your Signal Score?
Move four sliders to see how Sequencing, Stability, Rotation, and Perceptual Advantage combine into a single performance score.
UBKT takes four biomechanical metrics and rolls them into two headline scores:
Adjust Your Metrics
How cleanly energy transfers up the kinetic chain. (0 = broken chain, 10 = elite transfer)
Exponent: 0.50 (equal weight with ASC)
How stable your posture is under high-velocity rotation. (0 = collapsing, 10 = rock solid)
Exponent: 0.50 (equal weight with SEI)
Your power style — rotational vs linear. Higher = more rotational ceiling, but linear athletes still score well.
Assessment only (not in BSS formula)
How hard you are to read. (0 = fully readable, 10 = full perceptual advantage)
k=0.25 multiplier (up to +25% SSQ boost)
Hybrid Canon: BSS = sqrt(SEI × ASC). Geometric mean on a 0–100 z-score scale. League average = 50. DM and PA are separate companion scores. RDR is a diagnostic style metric.
RDR describes your power style (rotational vs linear), not quality. Linear athletes aren't penalized for being linear.
SEI uses a logistic sigmoid centered at K/BB = 2.65 (league average). Every point above or below 50 represents a measurable deviation from the documented league baseline.
Your perceptual edge adds noticeable value to your engine (+3-8%).
