Kudos to you for acknowledging your error and correcting it. We certainly do need more high IQ (>128) math PhDs with integrity, like yourself. Please do consider pursuing higher math in a full time capacity.
Would love to hear more about your analytics work in League of Legends. Is it fair to say that the "useful" numbers/stats tend to be low-hanging fruit and not particularly interesting / requiring of creativity? I imagine with a fairly dynamic meta-game, you're limited by the data available to you, which can quickly become obsolete.
I'd also imagine any data you can crunch from solo queue games is of limited use in competitive play.
