Analyzing the Skytrak numbers

[HHCPA]

Hey guys. First post here. I've got a new Skytrak and absolutely love it. Can somebody point me in the right direction to gain some knowledge about my swing numbers? I have no idea what some of that stuff means. I get carry, roll, offline, etc. I need a tutorial on PTI, desirable spin rates, etc.

Appreciate any direction.

PTI is Skytrak version of Smash Factor..
backspin rates are all tied to swing and ballspeed..
simple quick guideline is 1000 x club.. so 7i is roughly 7000,, 6i is 6000..
do u understand the modern ball flight laws? If not check YouTube .. it is a must
Driver will be somewhere between 1800-2700 for most... launch with driver is key as well as spin..
good luck

I'm all ears here also......

There is a tutorial on Skytraks website that tells you what a lot of the numbers mean but it doesn't say what all of the mean, along with the direction indicators and the color portion of the circles. I understand some of it but there is a TON of info to decipher.

Thanks for the response. I'll get on youtube and see if that helps. So far I have spent most of my time hitting irons and not driver or 3w. If my spin rate on an 8 iron is 6200 instead of 8000 what is that telling me? I average 145 yards with a PTI of 1.3. I'm happy enough with the distance (sort of) but have no idea if the 1.3 PTI is average or below. This should be interesting.

Don't get too caught up in the numbers.. search for Trackman pga stats on Google and you will get some info there. Remember that the PGA guys are PGA guys... Take a look at the LPGA #'s as well for comparison.

The 1000 rpm x club number is just a rule of thumb. There have been studies by Trackman showing that you can get reduced spin from the mat that you are hitting off of, and you might be a little low because of lower club head speed. The more important numbers are the launch angles and spin axis. Vertical launch angle is how high your ball is going. You can search for PGA average launch monitor numbers and find a Trackman chart, although LPGA is probably more realistic for most of us. If your launch is too high you can be flipping your hands so the club is passing them too early. If your launch angle is too low your hands are too far in front of the ball or you are hitting it thin.

Horizontal launch angle is mainly determined by your club face at impact. If it starts to the right, your club face is open (assuming right handed golfer).

Spin axis is determined by the difference between your swing path and club face. If you have hook spin, your club is more inside out relative to the face.

So a draw that starts right and ends straight is caused by a slightly open club face with a swing path that is more inside-out than the face angle (think 2 degree club and 5 degree path)
A fade that starts left and ends straight would be something like -2 degree club and -5 degree path

Most people strive to hit it straight, so first I would work on getting the launch direction straight (square clubface) and then trying to get the spin axis close to zero (square path)
