I don't want to post so much personal info, but I can say that despite having an quite far into level 5 IQ, and several traits from level five, my oldest (the only one I have numbers for) also has traits from all five levels, and is missing traits from levels one and two (not through a disability or delay, but just temperament).
And things like this, for IQ of 130:
Most of these children are a full two to five years beyond grade level by age six.
. I mean, really? To hear the teachers at our school tell it, it's very rare for a child to be more than one or possibly two years ahead in math at six, let alone for there to be a couple in each class who are doing fifth grade math.
