Makes me wonder if the contestants are not allowed to touch plates, post performance so that the tally by judges may proceed unimpeded. It should be obvious enough on tape if there was empty plate handling occuring, by whom, and let the chips fall from there.
Judges? The whole Nathan's Hot Dog eating contest is as bona fide as a wrestling match for the belt. The judges are likely paid with a hat, shirt, and all the hot dogs they can eat the day of the contest.
