I had to look it up to try to understand "slope" and "grade".
Quote Rivet, View from the Top:
"Grade is rise (vertical) divided by run (horizontal).
For example, 1000 feet over a mile is...
1000/5280 = 0.1893 = 19 %"
That makes the H3 about 20 degree angle slope and 30 degree grade.
I can?t visualize rise VS run, but I can visualize angles. I can add this to my dislike of the use of % for anything. Per 100?give me a break!
Best regards, Happy Jack
