Funny as it sounds there are actually techniques you can learn to make you faster. I forget what they are, sure google could bring them up though. Think it was things like using your other hand to move the controller etc.
A friend of mine used to have a tactic for when playing the first MGS and there is that scene where you have to withstand the electricity(?). He simply got an old AA battery, put some blu tak on the end to make it fit the button and would then use that while holding it in his hand lol.
