Renxin Tang (汤任欣) has been competing for 14 years. Her best event is the Megaminx: a personal-best single of 37.86, set at GDSY Open 2019, puts her in the top 1.1% of the 34,786 people who have ever been ranked in the event, and 27th in China. Until November 2014, no official Megaminx solve in the world had been that fast. Across 61 competitions since March 2013, she has put 2,374 official solves on the record across ten events. Solve to solve, her 3×3 times vary about 11% around a typical one, steadier than 88% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 10.22 in March 2013 to 6.88, a 33% improvement. Renxin has entered 61 competitions, more competitions than 99% 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.
