The same here, the elevation gains are completely exaggerated, even when I’m using trekking mode and following a route set by Suunto that has predefined elevation gain values
You assume that Suunto route has correct estimated elevation numbers and the watch exaggerates that. But in my experience it is the route estimation that is consistently low by 10-30%.
I compared that to other services like Strava, other devices like Garmin, and to the actual elevation changes captured by several models of Suunto watches. The app is clearly in the wrong when it calculates elevation gain for a route, not the other way around.
