My wife and I both have Fenix 6 Pro watches (latest 8.10 SW) and until recently both recorded a very similar elevation gain for the runs we do together, which I should expect.
However, for the past week my elevation has be approximately 100ft more than my wife's which is a lot considering our current routes are between 150 and 500ft.
The difference seems to accumulate closer to the beginning of the run then gains follow more closely, for example, after one mile tonight I recorded 141ft and my wife 36ft. It's definitely mine with the issue.
The altimeter is set to auto calibrate during an activity and we've also tried calibrating via GPS and DEM yet still record a large difference.
I'm now thinking I may need to factory reset my watch. Could this potentially rectify my problem?
If so, what about all the data on my watch, can this be backed up? If so, which files would I need to back up which I assume would just go back into the NEWFILES folder on reset?
Would I lose my V02 and all fitness based data?
Thanks for any help.
