Honestly that looks like superficial rushing for rushing's sake. There is so much advanced and deep elementary math kids could learn.
Just imagine how much more quickly a student could progress through a course if they were to work one-on-one with an expert tutor 5 days per week. Quite a bit more quickly in most cases. Well, our system effectively serves as an expert AI tutor and based on our calculations is on the order of 4 times more efficient than a traditional math class.
But I get the skepticism. I'd probably be skeptical myself.
