How to determine yards offline with GCQuad?

[youngun87]

I know That the app shows you how far offline your shot finishes up but are there any rules of thumb or tables someone can link to that give a good approximation of how far offline a shot will finish up and how many yards a fade or draw is? Sometimes i find it annoying to have to look at a screen to know where the ball ends up. I like how I can knowthe shot shape etc but I would like to be able to approximate how far offline my shots are for given ball speed (or carry distance) + sidespin + side angle and to be able to get an idea of how much the ball is drawing etc....

I figured out that every one degree offline the ball starts it equates to roughly 5 yards offline at 300 yards and 2.5 yards offline at 150 yards. Would be great to get an approximate curvature value based on carry distance and side spin.

Trackman University has calculators for some of this stuff, but you'd need to put in the leg work to make a workable spreadsheet. First you can use their calculators to find launch and spin axis based on face/path and they have some generic assumptions for offline and total curve based on a few spin axis values in some of their articles, so you could do a little interpolation and create basic offline calculation for various launch parameters.

The hang time matters much more than the carry distance.   So you'd need to base it off of launch angle and back spin and ball speed (not just carry distance).   At best you might be able to put together a separate table for each of your clubs based on average numbers if you wanted to put the effort into it.

Ugh yeah this seems like a lot of work. I think the easiest solution is for me to bite the bullet and get a cheap tablet dedicated to the GCQuad that lives in the carrying case. Foresight makes such great hardware and their software is obviously fantastic for ball flight data but their User Interface and graphics on SIM play is pretty much at the bottom of the category. Even launch monitors that are MUCH cheaper blow foresight out of the water in terms of UI and graphics.
