Anyone suspecting their Enduro is reporting higher Elev Gains than it should?

I've had my Fenix 3 HR since 2016 and through the years of competing in ultra trail races abroad, the F3HR had always been accurate when it comes to distance and total elev gains but perhaps slightly lower than the organiser's published numbers. Then when I got the Enduro I immediately started getting uncomfortable with the more generous elevation gains. It's running the latest software version for APAC model. Photo below from today's trail run, there's a 137m difference in elev gains between the two. What are your thoughts?

Same here: I start at 7m elevation and during a 3 hours ride there is a continuous altitude creep. It does register altitude changes (up and down) throughout the ride and I end up at 25m altitude at the starting location. My riding buddies have half of my altitude meters.

Very much interested in an answer and bug fix.

Did a follow-up test at the same location this time switching to 1 second recording. I was sceptical at first if this was going to make a difference but as you can see below, I'm happy with the outcome.
