Heat Acclimation is bizarrely weirdly useless

So I went for a ride today. A big one. It was hot. Really hot.

 

You can see the approximate point where the temperature went over 22 degrees. So, there I am, working REALLY hard in REALLY hot weather. For hours.

AND, my heat acclimation went down from 2% to 1%. Apparently, this is because it was below 22 when the ride started. 

WTAF Garmin??? Is this for real? Somewhere between my trusty Edge 830 and my Epix Pro Gen 2, the Garmin system can't figure out that it is blazing hot out? (Note that I have spent a few $$ on Garmin devices and am constantly telling people to get Garmin not Wahoo.)

Am I not doing this right, or is this feature an absolute joke? Yes, I gave Connect full permission to access the phone location, which is weird af cuz I literally have two Garmin GPS devices connected. 

OMG can someone make this make sense??

    How do you know/think it's only based on the temperature at the time you start?

    By reading the documentation, and confirmed by testing. As for the documentation, then for example here…

    What Is Heat and Altitude Performance Acclimation? | Garmin Customer Support

    Compatible watches and cycling computers provide acclimation notifications and corrections to your recorded VO2 Max Estimate and Training Status when the temperature is above 22ºC (72ºF)/ elevation above 800 m (2625 ft.) at the start of the activity recording.

    ... and also

    Compatible watches and cycling computers provide acclimation notifications and corrections to your VO2 max estimate and training status when the outside temperature is above 22ºC (72ºF). Temperature readings for this are based on the weather data from your connected smartphone rather than sensors in your Garmin® watch or cycling computer.

    That makes no sense for long rides.

    Of course it does not. And that's exactly why I am suggesting to request a change from Garmin, and use multiple legs of a multisport activity as a workaround, in the meantime.

    Ok thanks. So what does your biography mean? Were you a Garmin employee in the past?

    No. It is just the answer to a frequently asked question.

    I might be making progress on this. On my watch, (not the edge 830 used to record the activity) it seems to be getting incorrect weather data. The weather location is correct, (it has a weather map which shows me in the right place) but the current weather and forecast are wrong. I don't know how to determine whether the data that it is getting are from any actual weather stations in my area though.

    There are kind of 3 locations that play: 1 your watch (GPS), your phone (may be GPS but probably it's cell tower based, less accurate) and the location of the "nearest" weather station. Your phone's location can easily be off by a km or even more if you're far away from towns. The way the Garmin app decides where is the nearest weather station is not always what you would think.

    For what it is worth, I was in a city for the majority of the ride, and it was hot everywhere.

    From a suggestion from another thread, I changed the weather location on my watch to another location. I did this a couple of times. The weather forecast changed, but was still way cooler than the publicly available reports. Something weird is going on, I believe.
