NFL 40nDX NCAA

40nDX

"40 Index" (stylized as "40nDX") is a proprietary rating formula developed by Ross Wheatley with the intention to improve upon the traditional passer rating formula. The traditional formula was developed using antiquated and/or arbitrary performance standards. 40nDX reformulates the traditional convention by setting a more appropriate standard of excellent based on the 12 historic seasons in which a quarterback achieved 40 or more touchdowns thrown (hence the 40). A perfect 40nDX rating is 100.
