Elevation graphs seems to be smoothed

Hi.

I see that there is a fix in the new beta software (25 July 2018) for the Fenix 5s/5 regarding elevation error.
Do the Fenix 5X Plus have the same issue?

I have been suspecting too little elevation gain on my new Fenix 5X+.
Yesterday I did get elevation gain of 2435m on a long mountain run which I suspect is to little. My running mate got 3193m with Suunto. Strava "correct elevation" function gave me 2653m. A online route builder that I use give me 3161m.
