I have a Garmin 910xt a triathlon type watch but I am a runner and cyclist. It supposed to have barometric altimeter in it right? Well the data is seriously in conflict. I notice all the time when I upload to Garmin connect then Strava the elevation gain is way less than RIde With The GPS. I don't use RWGP but it uploads since I have an account. My Ride with the GPS always shows much more elevation gain. Today I went 53 miles and on Garmin the gain was 1165 and Ride with the GPS it was 1630. That is fair amount of off and usually that is close to what will be. I normally don't track this stuff I live in the flatlands but the data is suspect for sure. More fake news from something.

I don't have the watch but the barometric pressure altimeter is dead accurate. The problem I have with my 810 is that for some reason it gives me absolute ridiculous "max altitude" and "min altitude" of 35000 and 15,000 ft. But the change in altitude is correct.
