I can't attest to the accuracy of that vs. SportTracks correction vs. Training Center, though.
I made the change too and this brought the climbing down to what I had last year on my Hilly Hundred route.

But, this is still 15% higher than the GeoBike Profile provided by the club.

HOWEVER, when I compare the MB elevation profile to the GeoBike Profile, the peaks and valleys track with precise accuracy.

So, this seems to indicate to me that the elevation profile is accurate, but the cumulative count is off in some way.

Does this make sense?
