Xi Tan (谭熙) has been competing for 7 years. His best event is the Skewb: a personal-best single of 2.81, set at Shenzhen Nanshan Open 2024, puts him in the top 4.1% of the 73,281 people who have ever been ranked in the event, and 221st in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 12 competitions since August 2019, he has put 257 official solves on the record across seven events.

His Skewb best has come down from 3.99 in August 2019 to 2.81, a 30% improvement. Xi has entered twelve competitions, more competitions than 94% 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.
