Ivan Sosin (Иван Сосин) has been competing for 8 years. His best event is the Pyraminx: a personal-best single of 10.27, set at Belgorod Open 2019, puts him in the top 55.1% of the 129,321 people who have ever been ranked in the event, and 2,064th in Russia. Across 6 competitions since July 2018, he has put 96 official solves on the record across four events.

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.
