i don't know what you mean by power down. but you shouldn't change your tempo too much if that is what you mean. one thing to control distance is to think of your right arm as a clock arm. full swing with wedge is 11 try to have a 9 swing and so one and use the clock hours to learn certain distances. it may also help to choke way down, that will give you less distance with a full swing or less distance with a 9 swing, and different variations like that. your followthrough distance can vary too, to half followthrough and so on. try a bunch of differnent combos of thoose variations and see if any of thoose work.
