2×2 · top 12.8% of 186,767 all-time · competing since April 2022 · 2022ZHEN01
Jacob Zheng has been competing for 4 years. His best event is the 2×2: a personal-best single of 2.87, set at Queensland Open 2022, puts him in the top 12.8% of the 186,767 people who have ever been ranked in the event, and 971st in Australia. Across 7 competitions since April 2022, he has put 129 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 94% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 4 DNFs. His 3×3 best has come down from 17.30 in April 2022 to 13.81, a 20% improvement. Jacob has entered seven competitions, more competitions than 88% 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.
