I thought my question was quite obvious. I included the pictures to show the variation in max grade. I wasn't referring to the peaks and dips in the actual graph. I couldn't make the screenshot any larger. Sorry.

OK. If I ride from point A to point C, I will travel through point B. Point B is a hill that is, for instance graded at 20%. The first picture I included is of the whole route, the second picture is of a section/segment/climb within that said route. My question is, as previously asked, why the variation in percentage of grade when the hill/climb/segment is the same object? The hill doesn't move or shrink, does it?

Example: If I have five coins in my pocket, it doesn't matter if they are all in one pocket or in numerous pockets, there are still five coins. If I travel 10 miles, it doesn't matter if it's at 12mph or 30 mph, the distance is still 10 miles.

So, with that said, how can a climb have two different max grades when taken from the same route, as the pictures show?

I don't know of any other way to ask the question.
