So earlier this week I went through the first half of the power & distance tutorials and tried pulling my right shoulder further back at the top. Being a data geek i plug my stats into a dashboard, this chart shows my last 3 sessions, for around 30 driver shots per session. I gained average 10mph extra ball speed from this one small change and look at the distance gain. All I can say is wow...25 yards more with no change in accuracy! Can't wait to try again tonight.
What are you using to track distances?
