Well given you can't know what your family would be like, or your kids education levels would be without home schooling... your can't make too many meaningful observations.

From all the reading I've done on educational outcomes for kids, the number one predictor of educational outcome, is socio-economic status of the parents. Sometimes exceptional teachers can move kids outside of that, but most of the time, it's what (socio-economic) 'class' you are in, not classroom.

EDIT:

Surprisingly this doesn't hold true in Asia, their focus on education is amazing at bridging socio economic gaps (though the above observation still holds true, but to a much lesser degree).
