I guess I could join the "lose sleep over it" group or just learn to live with the differences. Elevation tracks differently, too, but gps elevation stats are always a bit hit/miss. Mission Control is always higher.

Elevation is never precisely the same across insteuments, not when using a barometer (as in iPhone) and particularly not when using GPS calculations. Top quality GPS cycling computers primarily use barometeic pressure sensors for elevation measurements.
