Jonathan Irvin Gunawan has been competing for 15 years. His best event is the Clock: a personal-best single of 6.25, set at Indonesian Championship 2012, puts him in the top 8.1% of the 32,048 people who have ever been ranked in the event. Until August 2010, no official Clock solve in the world had been that fast. Across 8 competitions since November 2011, he has put 119 official solves on the record across six events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 7 counted rounds. His Clock best has come down from 9.90 in November 2011 to 6.25, a 37% improvement. Jonathan has entered eight competitions, more competitions than 90% 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.
