I can't process the jump from 1:200 level 4 to "more than 1:1,000,000" level 5.

I think that when you define the levels by early milestones rather than by IQ, you're naturally going to have overlap. As I recall, she distinguishes level 5 insofar as these children must have the earliest possible milestones in every conceivable category. You can't be level 5 in one area; if you're not level 5 in every area, you're level 4. Hence the rarity. laugh I'm not joking, but I do think it's funny.
