David Broom has been competing for 9 years. His best event is the 2×2: a personal-best single of 1.45, set at Berkeley Summer 2023, puts him in the top 1.9% of the 186,767 people who have ever been ranked in the event, and 778th in the United States. Until November 2008, no official 2×2 solve in the world had been that fast. Across 10 competitions since July 2017, he has put 223 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 14% around a typical one; 74% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 23.73 in July 2017 to 10.42, a 56% improvement. David has entered ten competitions, more competitions than 92% 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.
