Keira Leng Sok Kei has been competing for 2 years. Her best event is the 2×2: a personal-best single of 2.01, set at Singapore Mini 2024, puts her in the top 4.8% of the 186,767 people who have ever been ranked in the event, and 83rd in Singapore.

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.
