Okay, so here's a baseline for Attackpoint's elevation algorithm.
I know that the "front" side of the hill is 185 ft (56m) and the back side 95 ft (29m) and AP has it as 66 and 33. So about an extra 10%.
I should have #justshownup this morning.
yeah, if I used climb numbers for anything I might try to fix things, but it's close enough and I can just let my watch do all the calculations/recording and not worry about it.
