Yuri Kobayashi (小林夕莉) has been competing for 3 years. Her best event is the 3×3: a personal-best single of 10.05, set at Tokyo Winter 2025, puts her in the top 7.6% of the 284,439 people who have ever been ranked in the event, and 331st in Japan. Until May 2007, no official 3×3 solve in the world had been that fast. Across 6 competitions since July 2023, she has put 55 official solves on the record across three events. Solve to solve, her 3×3 times vary about 10% around a typical one, an early reading from 7 counted rounds. Her 3×3 best has come down from 13.00 in July 2023 to 10.05, a 23% improvement. Yuri has entered six competitions, more competitions than 86% 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.
