Interesting discussion.

Now I'm not sure what to do. I read somewhere that the corrected elevation can be off too. For example riding next to a sharp drop off the gps could show you as on or off the road enough to jump your elevation up and down. Obviously barometric pressure isn't perfect either and can change over the course of a ride. It's not due to a specific site either. The above data was from ridewithgps.
Here is my ride today on garmin connect. 4,887 feet with elevation correction and 3,520 without. I consistently get more elevation using the corrected data. Wish it could boost my average speed too
