I think the Hoagies chart is not really popular the way it distinguish between WISC IV and SBV. I would say that chart is to be avoided. It just confuses people.
I have trouble with the college entrance age as well unless you are talking about taking one or two classes as opposed to f/t college. Lots of parents choose not to send their kids at such early age to college.
I personally love HG+ when it comes to both of my kids. I could count on the fingers of one hand how many times I've used PG for my DYS. It's not that I would think that DYS kids are not PG, but it feels different when it comes to my own child.
