Sure, Dazey.
And if you take achievement scores, too, without IQ scores, you add in even more kids. Some of those could be hothoused or "overachievers" (meaning goal-oriented kids who work much MUCH harder than the average kid--I hate that word, but I don't know a better term for that sort of insanely hard and driven worker), not truly GT according to the definition. I suspect there are a lot of these, frankly. We're in that sort of area.
Add in extra MG kids based on demographics, too, and the numbers are bound to be higher than average. But THAT much higher? Hmmm...
