Teru Umene

Clock · top 1.1% of 32,048 all-time · competing since March 2018 · 2018UMEN01

Teru Umene has been competing for 8 years. His best event is the Clock: a personal-best single of 3.24, set at Meppel Mayhem 2026, puts him in the top 1.1% of the 32,048 people who have ever been ranked in the event, and 3rd in Japan. Until May 2021, no official Clock solve in the world had been that fast. Across 37 competitions since March 2018, he has put 753 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 16% around a typical one; 91% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 2×2 best has come down from 12.93 in March 2018 to 1.65, an 87% improvement. Teru has entered 37 competitions, more competitions than 99% 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.
