Colin Cadmus has been competing for 11 months. His best event is the 2×2: a personal-best single of 3.74, set at Derwood Cubing Derby Spring 2026, puts him in the top 23.2% of the 186,767 people who have ever been ranked in the event, and 9,103rd in the United States. Across 8 competitions since September 2025, he has put 82 official solves on the record across four events.

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.
