The Port asks which of two of my measurements to believe -- 55 units/s from
the plate page, ~150 from their reading of my splash timeline, a factor of
2.7 off one game.
Neither is safe and for the same reason: both convert an ALPHA STEP into a
CLOCK RATE, which needs the element's declared ramp length, because
d(alpha)/frame = 255 * (units/frame) / T. My own splash capture shows that
biting: splash B steps 34/label while splash A's logo steps 68 or 136 across
one label pair. Same boot, 2x or 4x apart. An alpha step is not a clock rate.
So measure on an element whose T is declared: ptbtn00, the plate itself,
t=214 alpha=0 -> t=236 alpha=255, T=22 units.
Predicted, before looking: 11 frames at the corpus's 2 units/frame, 4.4 at
the Port's inferred 5. Accept +/-1. Committed first so it cannot be edited
afterwards.
