BTW -I'm mathematically challenged - how does one determine the percentage of incline/grade?
Seeing the pics, my reflex was getting up from my chair That's definitely a hill I'd stand on, unless it would go on for more than, say, half a mile.

To measure the incline %, just know how much elevation you gain in how much distance. Example: if you gain 5 meters elevation over 100 meters distance, that's a 5% incline, 50 meters over 1 km is 5% too, whereas 100 meters over 1km is 10%. The metric system makes this much easier to calculate!!
