Sergei Sidorov

3×3 · top 53.0% of 284,439 all-time · competing since January 2020 · 2020SIDO01

Sergei Sidorov has been competing for 7 years. His best event is the 3×3: a personal-best single of 25.20, set at Izhevsk Winter Cube 2020, puts him in the top 53.0% of the 284,439 people who have ever been ranked in the event, and 3,082nd in Russia. Across 5 competitions since January 2020, he has put 23 official solves on the record across one event. Solve to solve, his 3×3 times vary about 20% around a typical one, an early reading from 5 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 29.89 in January 2020 to 25.20, a 16% improvement. Sergei has entered five competitions, more competitions than 83% of everyone who has ever competed.

The story so far

Competitions

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
