10,000 is Chinese for "more than I feel it would be productive to count." I don't know if that's how he's using it. The qualifier that only a fraction are repeated is what makes me suspicious of the total. But I don't know, maybe the guy does it for a living, and maybe he really keeps a spreadsheet somewhere.
If I'm ever convicted of murder, I'll undertake a review of his results as a way of ensuring I spend as much time as possible in solitary confinement.
This statement skipped several intermediate thoughts, like "I would like to review this guys results. But I'm far too busy raising a family. But I don't really relish the prospect of a life in which I'd have time to do this. It sounds like a special kind of hell. Or maybe life in prison." I think you can fill in the dots from there.
P.P.S.
Actually, there's more. I thought a special punishment would be to be in solitary confinement working on this project, but you have to be pretty bad to make solitary confinement. Unless you were to bend the ears of everyone in the sound of your voice with grammatical prescriptives, then they would just kick one of the shiv smiths out of solitary and put you in. Yeah, I know I'd probably suffer other prison related hazards instead, but whatever. That's what was going through my head. Aren't you glad I usually leave you guys in the dark?
