Admittedly 1 foot of change might be too little for the resolution of the sensor to reliably perceive and should probably be handled as just "noise" in the data. Still, I can't imagine you not having 3 to 5 feet of change regularly and many times on a road in the flattest of routes.
You've obviously never been to southwest Florida. It's flat!!! 
And why are you so concerned with elevation loss? You're getting way too lost in the weeds
Iride01 . I'm not planning (or even expecting) my routes to be symmetrical in terms of elevation. Even if I gain 157 ft. of elevation over 50 miles and also decend 157 ft. on the same ride my computer is going to tell me I "climbed" 157 ft. It's not going to give me a reading of "zero" because I also "descended" 157 ft.. Yes, I can go into the menu and the computer will show both my elevation gain and elevation loss. And if it's a round trip starting at home and ending at home, my "net elevation" may very well be close to zero... but the topline elevation number is still 157 ft.
