Same with a flat first serve. While we like to think we swing 100%, in reality, it's 100% within our own individual parameters.
If we really swung as fast as we could, with maximum effort, our percentages would be rediculously low.
Speed and power always governed by CONTROL and REPEATABILITY.
Thanks, I will try variation
