Hi, all!
You may have noticed that I have temporarily withdrawn my article on
Driver Optimization. (Or at least put a "warning notice" on it.) The
data in it has been called into question, and rightly so. Since the
"data" is computer-generated, I need some real-world data to test the
accuracy of the various trajectory programs I use. I have three on my
computer, and may obtain a fourth. Now I have to determine which --
if any -- I can trust. It's a fact that they give different output
for the same input, so they can't all be right.
Anyway, I already have some data for "big hitters" (ball speed at
150mph and more), so I know that part of the answer. Now I need data
"for the rest of us". I'd like to request this from any members of
the discussion group that have it or have access to it.
I need the following data for a few hits in the range of 100 to
130mph ball speed. The data for each hit should be:
*** Ball speed
*** Launch angle
*** Spin
*** Carry distance.
I need each hit to be accurate. Reliability is far more important
than the number of data points. Three, or even two, hits in the range
will probably tell me what I need to know. The ball speed, launch
angle, and spin are obviously launch monitor outputs, but it is
strongly desirable that the carry distance be actual measured
distance. It should not be the prediction of a launch monitor, unless
you're working with a launch monitor that has been calibrated and is
known to give correct distance.
If you're working at altitude (more than 1000ft), I'd like to know
the altitude.
The hit should be at a reasonably comfortable temperature (60*F - 85*F).
The range should be flat so the landing area and teeing area are the
same height.
Wind should be negligible.
Thanks in advance for any data you can provide.
