Skill Score

After you solve a puzzle, Spectra shows a Skill percentage (0-100) that prioritizes solving without assists, followed by fewer attempts, then speed.

Formula

Skill=(0.8×E+0.2×S)×A

E=max(0,(1-RM×N)×100)(efficiency: 80% weight)

S=max(0,(1-T3600)×100)(speed: 20% weight, scales over 1 hour)

A=1.0 (no assists)|0.8 (one assist)|0.65 (both assists)

M = max attempts, N = item count, R = total errors made across all attempts, T = duration in seconds
