My mother used to say something similar. She still feels like 2 hours of school a day is more than enough to keep pace, even for NT children. And I do have to say that typical public school home tutoring schedules pretty much confirm that--if a student is on home tutoring from the public high school, it is quite common for that student to receive two hours of tutoring time per week (maybe two hours twice a week, if they have a lot to catch up on, say, after a psychiatric hospitalization), and for the state to consider that equivalent to the 5x6.5 hours a week that everyone else is getting.
