Hoagies webpage summarizes the approximate equivalent test scores. These are overall test scores, Full Scale IQs, not individual subtests nor GAIs. Various tests have different scores corresponding to 3SD+ from the norm, 99.9th percentile.
In reality, Hoagies doesn't actually answer the question. It's rather a clearinghouse of information about what various professionals think. And it should be clear that
there is not agreement. Some believe that PG should come down to include 145 and above because more modern tests don't differentiate between higher LOGs well, but...
these levels are still under investigation.
One ought not to conflate scores from different tests, as the levels of gifted (LOG) are distinct and represent progressively higher scores.
That is true, but all of the ranges are different, depending on the test. Some scale's notion of HG starts at another scale's notion of PG. EG is probably the most convoluted, which is probably why you don't hear the term standalone that much.
HG is not synonymous with PG.
HG+ is not synonymous with PG.
HG+ would include those who are Highly Gifted, Exceptionally Gifted, and Profoundly Gifted.
Simply stating this does not make it true.
I believe that the burden of proof is now on you to demonstrate otherwise.
