I mentioned speedrunning before in the context of mastery, but there is the other side of speedrunning that’s equally interesting: that utilizing bugs (or, glitches) to get the fastest possible time.

This 17-minute video by Msushi covers “one of the most loved and broken glitches in Portal 2” and the strange relationship the community has in following a bug to its conclusion – which, in this case, is not fixing it, but creatively using it to shave of speedrunning time. (There is an element of mastery there too, with spawning and despawning, but I don’t want to spoil the surprise.)
