Did the Skytrak Club Data Features Ever Get Implemented?

[Silver]

Hi, new here and tried searching without finding the answer, but I'm about to pre-order a Skytrak (finally ), I saw a year or two ago there was club face data on beta, so did it ever get implemented? Is it still a work in progress?

[GungHoGolf]

Club data (calculated dyn loft, AoA, swing path and face angle) showed up in a beta, but never made it to an official release. Unknown whether it ever will.

Thanks, did anyone test the beta? I read some posts the data was good, but maybe not up to the standard to release as 'reliable data'. More than fair enough. Any more info if it will still be implemented or if it's even being worked on appreciated.

I sold my SkyTrak before 3.4 came out but the calculated data was still in the DB files even after they turned it off from the beta in the version I had before. If you have Microsoft access you can get at it. It’s not on the fly on the screen so it’s not as immediate in terms of feedback but I’d also be careful studying one shot at a time with estimated data. I poked around and looked at patterns and averages from sessions to pick up trends as I was working on things.

The calculated club data is probably still in the db file, but as of v3.4.1 that file is encrypted and inaccessible by anyone but SkyTrak. I was using it for Advanced Analytics for SkyTrak, but now I have to come up with another method to get data in, and calculate those values myself. smh

Honestly, you probably could just do it yourself using a spreadsheet. The whole assumption is that the ball is struck center face. You then look at what combination of face and path creates that HLA and spin axis. Thin similar for AoA and dynamic loft. Ron's (from gunghogolf) analytics software does similar calculations.

To make a long story short, if you struck it center face, yes, quite accurate. You would need footspray to make this actionable from a shot to shot perspective.

I've had my Skyrak for a couple of years now and can definitely say it has helped my game. But one question I have had recently surrounds the spin axis and HLA numbers available on the lower right of the reading in the range app. Am I correct in reading a 5 degree open spin axis means that most likely the clubface was open at contact, and that the HLA angle degree can be more related to swingpath? I know these are not measured and it's reading the ball data, but my thinking it can be used to "estimate" the clubpath and face angle at impact. Am I correct in this?
So therefore a 5 degree left spin axis would mean a closed face and a 3 degree left HLA would be effectively a slight out to in path?

You have it backwards. HLA is mostly (around 85%) due to face angle at impact, and the path-to-face difference is 100% responsible for spin axis.

As GungHoGolf says. That is for driver. The higher the loft, the the lower the influence of face. For driver, each degree of difference between face and path leads to roughly 6 degrees of spin axis. 6 degrees of spin axis moves the ball offline 7 yards per hundred. So let's say that there was two degrees difference, on a driver swing that carried 300 yards (center face contact). Let's assume that for this particular shot, the influence of face and path offset perfectly so that the ball started out straight. However, it would curve 14 yards per hundred, or 42 yards total. Ouch.

GungHo and Morini - Thanks for the replies. I read the article and it makes sense. I think I understand it but I'm still a bit confused when I see my numbers, - I've posted some screenshots of my recent Skytrak session with a PW, 6i, and driver. They are all similar with a center HLA reading and a severe right spin axis. I am lefthanded, so these shots are hooks where they all start out dead strait, but hook off the planet. I wish I could get to a real range and see the ballflight for real, but at least for a while, I have no access and will not for probably until late May here in PA.
From my understanding of the article, my clubface is square at impact but I have a sever out-to-in path?? Is this a correct conclusion? I certainly don't feel the out to in, but then again, I hit probably 100 balls with about 90% of them looking like this, with the other 10% just plain bad. I did manage to hit one good 6i, which I did post so it's not like the unit is reading incorrectly. It's aligned perfectly and with a short wedge I prove it regularly. I know it's all my swing -
Anyway, just looking to get a little affirmation that what I have going on here is a swingpath issue and not a clubface issue. Although, I can't believe I can have a swingpath so severly out to in - I mean with a wedge 13*, and with the driver the 16* and 25*. Some of the drives not posted were above 30* - Is this possible - or do I have my thinking wrong here?
Much appreciated guys.
Here's to getting out to the real course sooner rather than later.

Lombo, I wouldn’t class most of those as hooks. You’re being hard on yourself.

Your correct in saying that your face was square to target at impact, but your path isn’t bad. It’s not out to in as you said but in to out, and only by about 3-6 deg on those shots.

i would probably keep the path as it is but try to have the face 1 or 2 deg open to target, then you’ll have a soft draw which starts left of target and draws back onto it.

Face could not have been square.To get zero HLA, either path and face are both zero, or one is positive and the other negative. Since there was significant spin axis, zero zero was not the case.

Lombo,

First of all, what is a hook, what is a draw? I guess it depends on what you are trying to do. I would call a shot that had 10 degrees more spin axis than intended a hook.

Anyhow those definitions are arbitrary. In order to understand what is happening, I'd drop the term draw, hook etc, and only think of spin axis, HLA and how it moves the ball.

I can't tell for sure, but it sounds is if you are a bit hung up on the idea that face is responsible for HLA and path for spin axis. Both are used in either calculation. HLA is a result of the COMBINATION of face and path. Spin axis is a result of the DIFFERENCE between path and face.

First of all, lets assume that all shots are struck center face (huge assumption). Also that your ST is aligned properly.

HLA for driver (85% face, 15% path)
Spin axis for driver: difference between path and face (in degrees) multiplied by 6.

Your 25 degree spin axis driver shot had about 4 degrees face to path difference.
It started out straight, so face closed (negative) and path in to out positive)
Using a little algebra, this means:
Face: 0.6 degrees closed.
Path: 3.4 degrees in to out


All assuming center face strike. A trackman analysis suggests that each dimple ball is struck off center result in 6 degrees of spin axis. I don't know if that is true for all drivers, especially modern ones.
