Zack Hall

Skewb · top 2.5% of 73,281 all-time · competing since January 2019 · 2019HALL02

Zack Hall has been competing for 8 years. His best event is the Skewb: a personal-best single of 2.38, set at December Series: Kensington 2021, puts him in the top 2.5% of the 73,281 people who have ever been ranked in the event, and 88th in Australia. Until February 2014, no official Skewb solve in the world had been that fast. Across 11 competitions since January 2019, he has put 474 official solves on the record across eleven events. Solve to solve, his 3×3 times vary about 15% around a typical one; 80% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 18.68 in January 2019 to 8.79, a 53% improvement. Zack has entered eleven competitions, more competitions than 93% of everyone who has ever competed.

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.
