A <.5% error when you're going up a 10% hill is hardly useless. For all practical purposes the horizontal distance works just fine.

All this talk of slopes, triangles and such has me yearning for some pi(e).

Yes that would work as well. :lol: About 2 years ago and 60 extra pounds I thought every hill was at least an 8 percent grade. I would punch the bike computer into alt mode and then go for grade and discover it was a 4 to 5 percent grade. I thought the computer was less than honest.:eek:
