Optishot strange swing speeds
Received my Optishot two days ago and I am still testing. Got some strange results using the practice range with the swing speeds. If I use the same physical club (6 iron) and only change the club selection in Optishot I get different swing club speed measurements (when swinging the 6 iron at the same speed). For example club selection set to:
9i -> swing speed 70mph
6i -> swing speed 80mph
3i -> swing speed 85mph
driver -> swing speed 100mph or more
Does anyone have the same experience? Is my Optishot defect?
