Jacob Shem
3×3 · top 8.2% of 288,433 all-time · competing since August 2022 · 2022SHEM02
Jacob Shem has been competing for 4 years. His best event is the 3×3: a personal-best single of 10.24, set at Tramsheds IX: June Saturday 2026, puts him in the top 8.2% of the 288,433 people who have ever been ranked in the event, and 754th in Australia. Until May 2007, no official 3×3 solve in the world had been that fast. Across 8 competitions since August 2022, he has put 153 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 14% around a typical one; 74% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 4 DNFs. His 3×3 best has come down from 19.46 in August 2022 to 10.24, a 47% improvement. Jacob has entered eight competitions, more competitions than 90% 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.
