Bullshit. He SAID what he was averaging over (badly). Having stated a scenario and used the word "average" in the context of that scenario, he has to average over what the scenario says he's averaging over.

Sure he can, BUT HE DIDN'T. The word "longest" does NOT appear in his question!

But the prospect of doing the experiment over does NOT arise in his scenario. He didn't ASK about that. He ASKED about doing the experiment ONE time.

Which was what the question was about.

No, HE won't, because HE'S an idiot, as you can see from the fact that he's still arguing against high school math, and still deluding himself that he can divorce "on average" from the average.

So is he.

No, he isn't. This is what he asked:

He is NOT asking for the LONGEST match. He is asking for the AVERAGE match.

Well, if you can keep track of a million flippers flipping a hundred times, you can keep track of the number of decimal places where the first digit less than 9 is.
