It supposedly references known elevation points on or near your route instead of basing it solely on barometric pressure. It usually changes quite a bit when I enable/disable.
Just tried the elevation correction and got 9,433 ft. Little bit lower than before but still about 5% off the trainingpeaks.com.
BTW I'm not complaining at all, I was just surprised to see those differences as I never really paid any attention to that
