Henry Cohen
2×2 · top 7.6% of 186,767 all-time · competing since January 2010 · 2010COHE03
Henry Cohen has been competing for 17 years. His best event is the 2×2: a personal-best single of 2.36, set at Battle of Appalachia 2012, puts him in the top 7.6% of the 186,767 people who have ever been ranked in the event, and 2,991st in the United States. Until February 2008, no official 2×2 solve in the world had been that fast. Across 9 competitions since January 2010, he has put 239 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 15% around a typical one; 86% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 6 DNFs. His 3×3 best has come down from 33.61 in January 2010 to 10.69, a 68% improvement. Henry has entered nine competitions, more competitions than 91% 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.
