VO2 max calculator seems kind of basic

I know it’s just an estimate based on pace vs heart rate, but still: doesn’t the watch collect data on altitude, elevation gain, temperature, etc. that would allow for a somewhat more elaborate algorithm/calculation?

Not everyone in the world lives in a flat city at sea level. I live in the mountains, so every day I go out running, if I pick an uphill trail my VO2 max will drop two points, then when I run downhill the next day it’s back up two or three points. I recently went to work in Miami and it was up 5 or 6 points overnight. Hell, even people who run in the same area at the same elevation year round report fluctuations in their VO2 max based on whether it is summer or winter.

TL;DR: I know VO2 max is only an estimate, but I think in this year of our lord 2026 we should expect a better estimate.
