Well, yes.

Although Rob's idea would be a patch for the apparent edge cases, at some point if we want accurate difficulty we need better maths, that's just how it is. I got so much shit for trying to make a calc, yet it's clearly the way to go, especially for a game like this with so many charts.

Edit:
The manual difficulty can only be the AAA difficulty. The AAA equivalency formula computes a score for any raw goods count. It is evident that the mapping makes 0 sense.
