Be careful of strava for calculating climb.

Position is used to calculate height, so position error and variation can translate to height error, and particularly on traverse paths that can add up to a lot of error height and illusory climb.

It is not so bad on straight up and down.

Now this may be that these races have been recording the 'climb' for years and years, and now modern technology allows us to measure more accurately...but I'm not so sure on that as actual distances are pretty much bang on. What am I missing? I ask because I am looking at some potential Junior Races, I have some nice courses but want to make sure I'm recording accurately from the start. Thanks.
