The map is not the territory.
Human concepts, like "gifted" and the various levels thereof, and various disability labels, are attempts to categorize the wide variation that exists to make more sense out of it. The boundaries of a naturalistic concept are not going to be sharp and clear. The question is what categorizations are
useful to make.
At this point, it doesn't really seem to make a difference which side of the "gifted" line you fall on (different people will draw that line differently, anyway). I understand the curiosity, but there is no One Real Answer Out There to find.
