发帖数: 10701 | 1 So, so far my conclusion about my approach to measure club speed is off
about 5-8mph, compared to Golf Smith 's laser detector.
So what's the off from?
Like I said yesterday, I doubt the off could be from golf shaft. In my
model, the golf shaft is considered to be made of "ideal material" which
never bent and torqued.
In reality, we know the golf shaft does bend (flex).
So I found this article, http://www.tutelman.com/golf/shafts/ShaftLab3.php,
(if you don't want to go through , just look for the conclusion.)
From what I read, the kick velocity of shaft will generate *up to* 10mph
club head speed.
Walaa~ It makes perfect sense for my model.
