Stamina decrease in the car!

I had a ride scheduled for this past Sunday and I wanted to do some recon on the route.

I used the Edge 1040 to navigate the 100 mile course. I was not wearing my Garmin HRM. The stamina data screen showed my stamina steadily decreasing during the drive. I thought the stamina would surely reset at the end of the drive when I discard the activity. NOPE!!!

How weird is that? Even with 7 hours of sleep with a 70 sleep score, my stamina did not get back up to 80%.

Is there a way to force stamina back to 100%? Why would it decrease from the 90% to 20% during a drive with no HRM attached?

I actually performed very well on my 100 mile, 10,000 ft elevation ride. The stamina screen was useless during the ride .

Is there a way to force stamina back to 100%? Why would it decrease from the 90% to 20% during a drive with no HRM attached?

Thanks.

the garmin's general approach to data is full of such kind of guesswork - this is why almost all of their metric is simple a garbage you just cannot take seriously

or, you'd need to understand how they work, I mean, how they work really, and that is almost impossible because garmin just does not provide info on that

stamina can be useful as an aggregation of your HR data (when it is not a random, arbitrary data, such in your case), the higher the HR the less the stamina will be

personally, I find it totally useless, as using all day (10-12 hours moving time) on XC terrain my stamina drops like 20-30%? you can imagine, such effort kind of kills you

maybe it could work for roadies, for short sessions
