Dean Lederer has been competing for 8 years. His best event is the Pyraminx: a personal-best single of 11.38, set at Sydney Open 2019, puts him in the top 63.2% of the 129,321 people who have ever been ranked in the event, and 3,766th in Australia. Across 7 competitions since October 2018, he has put 54 official solves on the record across three 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.
