    Hi CBTalbert,
     
    Sorry for the trouble. 
     
    We've seen a few reports of routes displaying unexpected elevation stats. 

    We're looking into this more and we plan to update our algorithm so that it produces more expected elevation stats in situations like this one.

    An elevation algorithm can spit out vastly different results based on how often you sample the points. For a mountainous track that has continuously undulating ups and downs, it's possible to get widely different elevations calculated, depending on how frequently you want to sample the points. It will be much higher if you include every tiny up and down. If you under-sample - peaks and valleys may get cut off and the elevation will be too low.

    We think the trick is finding the middle ground between what people expect to see, and what is most accurate.

    Unfortunately, I don't have an ETA on when you can expect this update to happen, but we are working on it.
