Andrey Koposov (Андрей Копосов) has been competing for 7 years. His best event is the 4×4 blindfolded: a personal-best single of 1:38.15, set at Supermiya PBQ in Tashkent 2024, puts him in the top 1.3% of the 2,174 people who have ever been ranked in the event, and 1st in Russia.

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.
