Tiancong Lu (陆天聪) has been competing for 7 years. His best event is the Pyraminx: a personal-best single of 2.51, set at Foshan Open 2026, puts him in the top 2.2% of the 129,321 people who have ever been ranked in the event, and 268th in China. Until January 2011, no official Pyraminx solve in the world had been that fast. Across 9 competitions since August 2019, he has put 259 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 14% around a typical one; 76% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 20.95 in August 2019 to 8.45, a 60% improvement. Tiancong 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.
