Skewb · top 28.1% of 73,281 all-time · competing since July 2022 · 2022SULA01
Lucas Sean del Rosario Sulaksono has been competing for 4 years. His best event is the Skewb: a personal-best single of 6.30, set at PSKG Premiere Cubing 2025, puts him in the top 28.1% of the 73,281 people who have ever been ranked in the event, and 303rd in Indonesia. Across 12 competitions since July 2022, he has put 189 official solves on the record across four events. Solve to solve, his 3×3 times vary about 15% around a typical one; 81% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 5 DNFs. His 3×3 best has come down from 1:12.76 in July 2022 to 37.10, a 49% improvement. Lucas has entered twelve competitions, more competitions than 94% 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.
