I feed power and performance to my horse who is a fairly laid back TB. I tend to give her a generous half scoop (stubbs scoop) when she is going to be working harder (eg a lesson or show-jumping competition - newcomers level), the evening before and the morning of the event. On other days I literally chuck a handful in her usual feed (alfa a, speedibeet and a mug of outshine). I think it is a good energy giving food, and my horse appears to do very well on it.
