Chesta A. F. Rosyadi

3×3 · top 4.0% of 284,439 all-time · competing since April 2019 · 2019ROSY01

Chesta A. F. Rosyadi has been competing for 7 years. Her best event is the 3×3: a personal-best single of 8.64, set at Solo Comeback 2023, puts her in the top 4.0% of the 284,439 people who have ever been ranked in the event, and 148th in Indonesia. Until July 2008, no official 3×3 solve in the world had been that fast. Across 9 competitions since April 2019, she has put 184 official solves on the record across six events. Solve to solve, her 3×3 times vary about 13% around a typical one; 61% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. Her 3×3 best has come down from 15.18 in April 2019 to 8.64, a 43% improvement. Chesta has entered nine competitions, more competitions than 91% 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.
