+1. to what the other posters said. That's a pretty lethal sprint power, but you need to be in contention (both in terms of freshness and location) in order to unleash it for maximum effectiveness. Sprinting, perhaps more than any other aspect of racing, requires a lot of experience. CDR is a master at hiding and then coming out at the right time (he's our version of Robbie McEwen) and posted quite a few videos. Watch & learn.
