hello.
I am also experiencing “big” altimeter changes (values changes from 490m - after calibration with the GPS . and then drops at 390m if I stay at the same altitude over 30 mins, without pressure changes - still 1021 hPa).
I also noticed that the leevation gain during my workout has doubled for the same route, I believe since abou a month or two. Usually it would be 100m elevation gain and now it’s to 200m.
As shown on the screenshot, there is a drop in the middle (from 551m to 417m, gray shaded curve) ; I took a break (auto pause on) and did not go high or down.Screenshot_20241224-140319.png I guess it’s the auto calibraiton with FusefdAlti that does its job after a few minutes ?
But why the fluctuation when I stay at home jus after re-calibrating ?
any idea about the reason for this stranfge beahvior ?
I am using the S9PP with FW 2.37.48
I checked the forum about this issue but could not find similar cases.
thanks
Florian
