3×3 blindfolded · top 4.7% of 12,178 all-time · competing since October 2015 · 2015OHHA01
Ha Min Oh (오해민) has been competing for 11 years. His best event is the 3×3 blindfolded: a personal-best single of 32.16, set at Asian Championship 2016, puts him in the top 4.7% of the 12,178 people who have ever been ranked in the event, and 13th in Republic of Korea. Until April 2010, no official 3×3 blindfolded solve in the world had been that fast. Across 8 competitions since October 2015, he has put 215 official solves on the record across 17 events. Solve to solve, his 3×3 times vary about 15% around a typical one; 89% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 4 DNFs. His 3×3 best has come down from 12.10 in October 2015 to 9.36, a 23% improvement. Ha 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.
