So, yeah, I'd say that each time you're mowing your lawn up hill, I count that.
Well I didn't know the discussion is how to calculate the data. The question is more about when to accumulate the data Specifically elevation or the change in elevation.
And even more specifically why some data didn't accumulate to provide the same number.
