I collected some data this morning and I think it was a fair enough data capture to post on it now (albeit setup still not perfect).
Setup:
- Indoor hitting studio with 8' TM4 and M+ to ball and 20' of ball flight. I put M+ in Short Indoor mode as it's what I can use at home.
- TM4 and M+ were setup beside each other because I couldn't move TM4. The Mevo+ was off center which is the second time I've done this test and the first time I had the M+ on golf side of TM4 and this time it was on opposite side (this matters in observations).
- TP5 balls with metal dot.
- FS Golf App vs TM Studio (so flight algorithms vary)
- After the first shot neither device had a no read (for whatever reason my M+ first ball every session is 0 mph ball speed and blank every other field then it works fine).
Commentary:
- I hit the ball awful with lot's of misses (mostly left but some right). This was probably good for testing so I left in all the shots regardless how bad they were. But it's never a good sign when later in my lesson I was hitting 3 hybrid with 150 mph ball speed and in my warmup when I captured this data I struggled to get driver above 150.
- The HLA is consistently about 2* left on M+ vs TM4. I had the same issue last time I tested but it was the other way. This has me convinced HLA is accurate but offsetting the device as much as I have to in this test has an influence even using the centering feature in the app (I'm simply moving the aim line too far I think). I also see very close to zero HLA at home hitting a centered string in my net. I'm not sure how much if any influence this could have on the spin axis.
- On a tech support call with FS a couple weeks ago when explaining my issues I had mentioned testing next to TM4 and they suggested the two radars could interfere with each other. Given most of the data looks solid they may be cautious on this statement but I should note it.
- I will post attach the data so I will only make a few broad statements on data.
- Carry distance M+ was a bit short in the longer clubs and a bit long in the wedge. The wedge isn't obvious to me why as the ball data seems pretty similar at quick glance.
- Total spin readings are either extremely close or very different there is no off by a little. In the low spin driver/3 wood on TM4 vs high spin on M+ I actually think the M+ was correct. I was hitting those clubs terribly but I simply don't hit many shots at 2k or less spin in general.
- HLA is discussed above but I will reiterate that I think M+ is bang on despite my data suggesting it's left biased.
- AoA needs more testing as my last test I got pretty close and this test the M+ was almost always way steeper. I was focused on ball data today.
Spin Axis:
- This gets it's own section.
- For SW it was almost an exact match on both devices on all shots and I would say 7 iron was pretty darn close also.
- For 4h, 3w and driver gear effect must be driving a lot of difference. I had the TM4 impact location up as I was hitting balls and I was not hitting the center often (as the ball data will show you). Many of the shots where the devices produced different shot shapes it seemed like TM had picked up gear effect and M+ did not. I know FS has said they are measuring spin axis and maybe they are but my testing suggests its being based heavily on club data. Any time the flight shape differed it looked like TM4 shape made sense considering gear and M+ looked to ignore it (i.e., heel strikes hooking on M+ but not on TM4 and toe balls coming back on TM4 but hanging on M+).
- I was able to easily hit push draws and pull cuts now on M+ when I couldn't hit push draws easily before. So I do think things are getting better and I need to hit the center of the face to see if that gives good results but the massive flares right don't seem to be an issue that I had before.
I have to run out and this took longer to type up than I had thought so I'll try to post the spreadsheet of data a bit later.
