I'm having trouble getting the correct distances, or what I believe should be the correct distances. My club head speeds seem consistent, but ball speeds are not. Every now and then I catch one flush, and they seem to be close to what I expect. Just hard to believe I would be short by 20 to 30 yards most of the time. I'm never that far off when playing a regular round out on the course. Would a factory reset do any harm or void any warranties?
