I don't have a lot of stats, but probabilities for 2E and high IQ wouldn't multiply like that (going from 1e4 to 1e6). The two components are highly correlated, so mathematically, their probabilities would be of similar order. The correlation grows starting at around IQ of 125 and reaches almost 0.9 at 160, meaning that majority of the HG+ individuals are not neurotypical, but it could be very minor.

I'll find the references and post it.
