Instinct altimeter goes bananas

Yesterday I made 15km bike ride in my neighbourhood... the maximum height difference is about 40m... I started at home at 33m, somehow went to over 1500m and arrived back home at 250m

I set to auto calibration based on GPS (I presume), stayed on the roads, calibrated 3 time during the trajectory... nothing works

- how do I calibrate and set the watch correctly?

- Is riding the bike or running a problem for the altimeter?

Thanks for a your help...

I did some tests. I performed a calibration as accurate as I could, with introduction of current altitude and barometric pressure and then observed the pressure and altitude over time both in a fixed location…

Thanks. I'll experiment a little with that. At least I got a better idea on how it works and what influences and routes to improve in everyday life.
