OK but buying a Kaplan SAT preparation book illegitimate?
Also, it would depend entirely on how many hours those additional resources you described are taking up. If the kids are just doing an hour or two a day, and they're still finding plenty of time to play afterwards, no worries.

If the enrichment is displacing all free play time, they're not on a healthy trajectory: paper
Not all of the activities I listed were done at the same time, and I don't think my eldest son has averaged more than 3-4 hours a week on them, while my younger children, for whom 2 to 3 20-minute sessions of EPGY per week have been their main afterschooling, have spent less time than this.
