Deting Qi (戚德廷)
Square-1 · top 0.66% of 25,272 all-time · competing since August 2025 · 2025QIDE01
Deting Qi (戚德廷) has been competing for a year. His best event is the Square-1: a personal-best single of 5.81, set at Zhengzhou Zeal 2025, puts him in the top 0.66% of the 25,272 people who have ever been ranked in the event, and 9th in China. Until September 2017, no official Square-1 solve in the world had been that fast. Across 4 competitions since August 2025, he has put 38 official solves on the record across two events. His Square-1 best has come down from 8.89 in August 2025 to 5.81, a 35% improvement. Deting has entered four competitions, more competitions than 78% of everyone who has ever competed.
Standing, event by event

|---|---|---|---|---|---|
| Square-1 | 5.81 | 11.17 | top 0.66% | 9 / 1,362 | |
| Clock | 17.83 | 21.25 | top 58.2% | 1,325 / 1,843 |
Percentile against all competitors ever ranked in each event, a fairer measure than raw rank, because the pools differ by a factor of ten.

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.
