Calculate club path number from SkyTrak readings?

[Ryan_luan@yahoo.com]

Is there a way to calculate Club Path number from the SkyTrak readings? SkyTrak reads side spin and face angle. Take this example from a driver shot:

1. Face Angle 2 degree to the right;
2. Side Spin 300 to the left;
3. Spin rate at 2500 RPM;
4. Carry 210 yards;
5. Land at 5 yards on the left.

is there a way to tell the club path number?

You can guesstimate as much as you can, but nothing replaces a measured reading. Purchase Rmotion and you'll have the club data u need.

[DirtyGarry24]

I say you can to a certain extent Ryan. You have to be careful though. You miss attack angle and toe/heel hit info so it can be misleading. You probably already know that though. I'm not 100% sold and some have said no without a good explanation of why not. I'm personally in the camp that you can get close but would love to hear more on the discussion. Great post! 👍🏼

Agree above that Rmotion could really be the answer here...

[Brutaly]

Both yes and no.

Path/face angle/angle of attack can actually be calculated almost as exact as if they where measured if you can measure vertical launch, horisontal launch and the club heads loft.

Approx 75-80% of the vertical and horizontal launch angles are created by loft and face angle. This means 25-20% of the launch angles can is created by the path. Try to exclude toe heels etc from the sample.

If you have those values your calculations can be just as good or better compared to a device like Rmotion.

There are also spreadsheets with entire flight models that you can use.

All you need for practice can be found in a Skytrak or similar as long as you combine it with some knowledge about why the ball behave as it does when leaving the surface of your clubface.

I fit clubs for customers and i swapped my flightscope for a skytrak and as long as i have some notes about how to calculate angle of attack i never fail with a driver fitting, even without actually measuring the angle of attack like my flightscope did. The same can be done with club path.

I can recommend this book:

You will learn some pretty neat stuff about clubs and understand some pretty sweet things about ball flight and how to explore your path/angle of attack without actually measuring it.

Is it easier with flightscope, definitely, but it is not necessary.

It's a good question, and theoretically, yes, you can calculate path with fair accuracy from those numbers, as long as you assume center clubface impact so gear effect isn't in play. It'd be cool if SkyTrak would show the calculated path number.

Minor note: SkyTrak doesn't measure Face Angle as you state in your question. It does measure horizontal launch angle, but as a previous respondent mentioned, HA depends on mostly FA but also some path.

[Ryan_luan@yahoo.com]

I read a bit about RMotion, but not clear on 1) how accurate it is; 2) the adverse impact at least mentally by attaching physical weight to the shaft (it is light but "I know it's there") 3) if The Golf Club software is required to use RMotion with SkyTrak. I do not have the Golf Club and don't want to buy it for RMOTION only. All in all I doubt that RMotion can provide accurate reading, but welcome to learn more it.

[Rapsodo]

Ryan the TGC software comes with it, so all you purchase is R-Motion. If you like to play online, you may need to upgrade the TGC license. You can see the details on our web site www.rmotiongolf.com

[DirtyGarry24]

Do you not get basic range function with rmotion purchase? I don't have it (yet). Thought you got something though, otherwise kinda useless right? I have Skytrak and TGC, so not an issue for me. Trying to help OP, could easily be wrong here.

[Rapsodo]

DirtyGarry24 you get 15 courses plus a driving range with the R-Motion and TGC license included.

This is intriguing, would you mind sharing more info and maybe one of the spreadsheets you reference?

Sorry for taking so long answering you but summer has blocked me from my computer and work shop :-)

Regarding the math and logic when calculating path and AoA i dont want to get into a lengthy conversation so i keep suggesting the above mentioned book.

When it comes to spreadsheets and tools you can use i think Tutelmans TrajectoWare Drive version 1.0 is the best one that is free.

You just need to sign up for his forum and download it. It was a while since i downloaded my software so i hope its still working.

http://www.trajectoware.com/

In his forum/site you can also find other tools and reviews of tools.

http://www.tutelman.com/golf/

Besides that i can recommend anything that Tom Wishon has written and also his own site.
www.whishongolf.com
There you can find out what a proper fitting really is and also find some great litterature regarding club fitting. If you understand proper clubfitting its no issue at all understanding your own swing and why the ball behaves as it does.

Tom W is also really active on some of the large us golf-sites and a very honest and straight up guy that genuinely tries to improve the game of golf and not mainly sell clubs. Try golfwrx if you want to check him out...

It takes some reading but its all out there.

Trajectoware works great. Thanks for the information.

Cool! You are welcome.

We are working on this. However, as others have stated, it's very difficult to accurately calculate club data from the measured ball data when there is a mis-hit. All we can do is to try The best bet is integrated systems that can measure that club data.

[Brutaly]

The best bet is integrated systems that can measure that club data.

You said back in May that you were working on a solution and it was a couple of weeks away before you could talk about it. Isn't those "couple of weeks" passed by now? ;-)

You need to spill the beans and i just hope its not a device you attach to the club (which was all ready communicated) but a radar/optic solution you were teasing about.

[SkyTrak_Seth]

You assumed that I was talking about earth weeks

The idea is to have several options.

[bennyg211]

Several options = good plan.
FYI, the app is looking fantastic. You guys have built something pretty special now and I think the interaction that you provide on this forum, along with the product, makes me as a consumer feel very valued. Well done guys. Looking forward to the what the future brings.

[magoo016]

this an older thread but I'm posting on all i can find to ask questions. I've been fighting a push/hook for a year now and recently got a lesson. I found out my path if 6+ degrees in to out. So that is obviously WAY too much and any real improvement has to fix that. I enjoy the grind to fix something, and I have an ST, but i need solid feedback from a practice session so i know i'm not going the wrong way, or mis-reading what is happening based on ball data only.

SkyTrak_Seth,
you have other treads talking about the beta test of club estimations (v3.1 i think), so obviously not everything has been worked out. I also saw videos from 2018 PGA merch showcase where it appeared the "Shot Optimizer" part of the ST range was replaced with a selection called "Club Data" (i think). What is the latest on that development? Also, are here any talks about a possible additional equipment integration? Maybe something like GC2's HMT?

As for the R Motion option discussed here, i've looked into this and there is an issue. It only works with ST if you get the TGC software. that's by no means a deal breaker, but here is what is: you CANT export the swing/ball data collected while using TGC and R motion on the course, or a TGC range session like you can on the ST practice range. the practice sessions of the ST are what i love the most, and i like to export the data and actually do some analysis on it to find the tendencies and patterns for bad shots. If i cant get that data out, then its just not worth the extra cost of the R motion and the TGC software. so anyone who goes that route should keep that in mind.

thanks for ANY info anyone can give me.

If you enable SHOT RECORDING in TGC, you can view and export shot data to CSV (excel import): http://golfsimulatortours.com

[magoo016]

aaaaaand now i'm off to buy the R motion

[Dave Lee]

Getting rmotion and tgc might be overkill if you are only interested in club path. Skypro, zepp, or blast might give you the info you want without having to get tgc (they are also cheaper than rmotion). Or the free method is just draw a line along your shaft line at setup. You can tell how in to out you are swinging by how far under the club head is going under that line.
