Peter Ha has been competing for 4 years. His best event is the 3×3 one-handed: a personal-best single of 7.75, set at CubingUSA New England Championship 2025, puts him in the top 0.16% of the 73,695 people who have ever been ranked in the event, and 24th in the United States. Until May 2015, no official 3×3 one-handed solve in the world had been that fast. Across 27 competitions since July 2022, he has put 507 official solves on the record across four events.

His 3×3 best has come down from 12.42 in July 2022 to 7.16, a 42% improvement. Peter has entered 27 competitions, more competitions than 98% 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.
