Calin Zamfir has been competing for 4 years.

Until December 2011, no official Clock solve in the world had been that fast. Across 28 competitions since October 2022, he has put 786 official solves on the record across eleven events.

His 3×3 best has come down from 33.25 in October 2022 to 10.83, a 67% improvement. Calin has entered 28 competitions, more competitions than 98% 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.
