Another consideration is that you probably don’t need the Powermatch with the Neo as it closely matches PM’s.
Out of curiosity why would you not use power-match? I like that I have one source of power for both indoors and outdoors.
I also like that Garmin Vectors measure power more closely towards the source, while Neo measures more at the hub.
This was generally aimed at the OP who has been having data transmission issues.
For years my primary training software has been PerfPro. Drew was providing metrics on trainer load, trainer power and power meter power differences well before these were added to main stream software. Back when I started with PP it really illustrated the issues with wheel-on trainers such as the CT and how much power varied at the trainer vs. PM power. It changed the way I calibrated, so that my first 15 minutes+ of follow on rides weren't off so far on power. It also convinced me that most folks using wheel-on trainers probably were way off on their power readings and that virtual power (with no PM to calibrate) was even worse.
With PP I could see in real time when my CT would drift from my PM. With the Neo I just don't (can't?) see much in the way of difference in real time. Power is so stochastic that chasing minute differences varying across a second seems somewhat futile. Are these adjustments happening quick enough to catch up to the last difference? I'm not sure the resolution here is fine enough for the difference to matter against an average load. Powermatch first hit mainstream to deal with trainers that were returning power readings well off what a hopefully reliable PM returned. And things could always go the other way if the PM isn't zeroed before each ride or drifts during the ride.
That's my general take with the Neo anyway. No belts, no calibration, etc. I don't worry too much about the one PM being the control as I have PM's on all my bikes and I'm sure each is slightly different than the other. But no worries or criticism of someone that uses a different approach.
