I'd wager that opening sooner versus later is almost certainly more pertinent than you realize there. It is comical how rapidly families get sick when they first start something like preschool. The longer it has been since they were exposed, the more rapidly they get sick.
That said, I'm happy to see data backing this. Last time I recall the claim getting looked at, it didn't have anything actionable. Private school was something like 1/20th the size of typical public schools and the numbers were inline with what you would expect for such a smaller population.
Our kids in public similarly saw a ton of reported cases. Around here, though, masking compliance was pretty good. I'm still finding stashes of masks we had in convenient locations for when we were out.
