In many competitive sports, the top players will all plateau at nearly the same level of performance. Distinguishing competitors any further becomes impossible, with what is effectively random chance deciding (honest) winners. The search for an "edge" - some split-second advantage to go from being effectively tied at #2 with 30 other competitors to being consistently #1 - leads competitors to do one of two things:
- Embrace superstition
- Cheat
Schmooey's actions are explainable purely as a way for an otherwise amazing competitor to get their "edge" by cheating "just a little". The same mechanics are why many sports not only have problems with doping[0], but organized doping rings that expend lots of time and energy on figuring out how to beat anti-doping tests. The face of sport is great athletes either making themselves very slightly superhuman with damaging drug abuse, or, if they can, lying about their performance to make it look like they did the former.
