^^^This. I and many of my riding friends use Wahoo to record and our elevations can vary by hundreds of feet on a ride. The Strava elevation correction reduces the variance substantially. It doesn't matter to me which is correct as long as I have consistency. To further muddy the water, we use RWGPS to plan routes. We rarely end up with the predicted elevation. Sometimes more, sometimes less. I can't see how a few hundred feet would matter either way.
