Ron Sheffi has been competing for 4 years. His best event is the Clock: a personal-best single of 4.93, set at Cubing for Yuval Israel 2025, puts him in the top 4.2% of the 32,048 people who have ever been ranked in the event, and 12th in Israel. Until April 2015, no official Clock solve in the world had been that fast. Across 11 competitions since December 2022, he has put 320 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 14% around a typical one; 71% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 19.94 in December 2022 to 9.98, a 50% improvement. Ron has entered eleven competitions, more competitions than 93% of everyone who has ever competed.

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.
