I'm trying to gather a list of people who have participated in the most International Science Olympiads. If you've participated in more than one and want your "record" on here (or know someone who has one), just notify me somehow in the comments or whatever.

Consecutive participations in the same Olympiad doesn't count for the purposes of this list.

There's probably more than this and I've heard of several incredible people so they definitely exist...
