method: re-correct the pacing entry -- their argument was wrong, my original reading was right

They measured what they had argued: the player presents 28 % of S00A's frames and
47 % of ADV's. S00A held real time BECAUSE it dropped three frames in four, so the
overrun is not evidence against skipping, and the entry I rewrote on their argument
was correct before I touched it.

I corrected a correct entry on an argument, having just written that a consumption
counter is what makes an audit. Accepting an argument from an absence is the same
error as making one.

Their figure is also a spread, not a value: 146.42 / 146.60 / 140.77 s = +2.4 % to
+6.7 %, n=3, load-dependent, and a lower bound measured under skipping. Both places
this corpus quoted +6.7 % are updated.
