That is also why cheating done by actually skilled people is really dificult to detect. Schmooey is a skilled guitar hero player and therefore he very well knows the limitations in terms of the results the competitive gh community will believe him. A random kid with no skill would have no idea of what he is actually doing and would just perform some absolutely unreal run that nobody would buy into. It's a bit like cheating in chess where a grandmaster using an engine would not blindly play the best moves but rather the ones that seem barely within human capabilities. Or like a professional runner on EPO who breaks the world record in the 10000m just by a few seconds although he would have had much more left in the tank.
