When I got 1550 perf solving ABC in the last round I became angry, but, somehow curious.

I made a survey on the Standings of my 5 last rated rounds.

I define the "pro alt rate" = P(you haven't reached cyan | you got GM perf in this round). Pretty Good.

R967 (Recent): 16/77 participants. 21% pro alt rate.

Edu R169: 9/71 participants. 13% pro alt rate.

Edu R168: 13/72 participants. 18% pro alt rate.

R960: 9/68 participants. 14% pro alt rate.

R958: 13/61 participants. 21% pro alt rate.

Man! What can I say! It's terrible! 1 in 5!

Mike says no alts, but somehow that's useless.

(Tips: The Chineses and Americans made the most alts, not the Indians. I noticed that, do not argue.)
