Seems like there is some interest in learning these lifts here, so I posted these vids. Just for clarification, when you clean or snatch and "rack" the weights with your hip crease higher than your knees, that's when they are called "power." If you squat to below this to rack, they are called squat snatches and squat cleans, or just snatch / clean for short.
At least that's Coach Pendlay's view on calling a lift "power"
