There's overwhelming evidence for the theory of evolution. There is as much evidence for rubberbanding as there is for the Flying Spaghetti Monster. My repeated assertions that the Flying Spaghetti Monster is the one true deity in the universe are unlikely to convince anybody of its existence, especially if these assertions are derogatory and mean towards non-believers, misrepresenting a lot of their claims.
You're actually missing the point Sam is making, which is that a lot of what people call 'rubber-banding' is a result of poor stamina management. Don't be quick to judge when you don't even understand the other side's argument.
