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!
Mike says no alts, but somehow that's useless.
(Tips: The Chineses and Americans made the most alts, not the Indians.)
