Looking over the numbers, I seems I get a consistent average of elevation under-reported ~5%, and distance by 1%. Sounds like nothing, until you extrapolate it out over the past couple years-- Strava has eaten about 175 miles and 38,000ft of climbing. Jerks.
Yesterday I did my first big ride with elevation gains since 12/17, including Newport Coast Hills in Orange County, CA. To my surprise, I lost ~10% of my Gamin 800 elevation after letting Strava calculating it. I've done same route tens of times and I always gained >30% more elevation using Strava.
The monthly strava climbing challenge will become a lot more difficult this year.
