Does anyone have any idea how I can convert the distance off the tee to a rough idea of what my swing speed is? I had it checked earlier this year, and it was around 107 or so then. However, I was struggling with my swing at the time, so I do not feel that those numbers are accurate now. I am averaging between 310 to 325 of the tee with my driver(yardages verified with the skycaddie, for what it is worth), and it does not seem possible to get that distance out of a 107 mph swing speed, or is it? I play close to sea level(eastern NC) and spin was around 2500 or so on the launch monitor earlier this year.
