Sophia Dumergue

2×2 · top 6.8% of 186,767 all-time · competing since May 2023 · 2023DUME02

Sophia Dumergue has been competing for 3 years. Her best event is the 2×2: a personal-best single of 2.27, set at Perth Autumn 2024, puts her in the top 6.8% of the 186,767 people who have ever been ranked in the event, and 516th in Australia. Until February 2008, no official 2×2 solve in the world had been that fast. Across 38 competitions since May 2023, she has put 799 official solves on the record across 13 events. Solve to solve, her 3×3 times vary about 14% around a typical one; 62% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside her 11 DNFs. Her 3×3 best has come down from 44.18 in May 2023 to 17.49, a 60% improvement. Sophia has entered 38 competitions, more competitions than 99% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
