What we did was increase awareness - which accounts for a small uptick in Autism per "X" amount of kids. That would be lkely to double the amount of diagnosis, sure. So seeing it go from say 1 in 1,000 to 1 in 500... Sure, that much of things can be attributed to awareness.
To go from 1 in 1,000 to 1 in 32 though - isn't because of awareness. That's engineering.
