All your graph does is look at a single dimension. You need a 6 or even 7 dimensional graph to really do it. It's too complex to ever be generalized as you are trying to do. If you want remotely accurate results you'd have to do it case by case every time.

It only looks at whether it'd be efficient in terms of gold/gold of AD. It's also outdated and it only affects Bonus Armor now.
