Those statistical projections are way over-inflated. Among NUMATS kids alone, there were already way too many perfect scores in math and quite a few in Reading among 7th and 8th graders. With the lower ceiling on the current SAT Reading, there are bound to be even more perfect scores. You add in other high scores that fall below perfect, the field will become quite crowded. Old SET literature suggests that 700 before age 13 used to approximate 99.99 percentile but I believe that is also inflated given the different curriculum and exposures and opportunities kids get today versus 30 years ago.
