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.
The reminds me of a very interesting story I read about "King" Richard Petty back in his NASCAR days. It was just one of many stories in some racing history book.
In any case, Petty apparently always won his races pretty closely. So he obviously only had a slight advantage over his competition... except that there were cases where some mishap (e.g. in the pits) left him multiple laps down (I believe as much as 7). He'd recover every single lap and then still barely win the race. No one ever thought to check his car for cheating because he didn't appear to be crushing the competition if you didn't realise he would have been capable of winning by probably dozens of laps or more.
