Different route, similar issues.
2022-04-20: Suunto +616m; TP +571m
2022-05-04: Suunto +575m; TP +665m
I realise this is a non-issue if there’s no statistical bias, i.e. overestimates and underestimates roughly cancel out. Not clear that’s the case. I will contact TP to see what they say – not much point contacting Suunto given their lack of interest.
Screenshot is of elevation correction in TP for yesterday’s route. Note that Suunto app has 575m vs. Suunto reading flowing through to TP of 587m!
