Dulina Harshitha Pieris
Skewb · top 3.7% of 73,281 all-time · competing since April 2022 · 2022PIER02
Dulina Harshitha Pieris has been competing for 4 years. His best event is the Skewb: a personal-best single of 2.71, set at Colombo Cubing Revival 2025, puts him in the top 3.7% of the 73,281 people who have ever been ranked in the event, and 4th in Sri Lanka. Until February 2014, no official Skewb solve in the world had been that fast. Across 11 competitions since April 2022, he has put 480 official solves on the record across eleven events. Solve to solve, his 3×3 times vary about 14% around a typical one; 66% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 5 DNFs. His 2×2 best has come down from 5.75 in April 2022 to 3.11, a 46% improvement. Dulina has entered eleven competitions, more competitions than 93% 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.
