the game does weight deep runs pretty hard, but it weights W/L pretty hard, too. theres a huge difference between an elite 8 as a 14 seed and an elite 8 as a 1-2 seed (see season 75). if you lost in the 1st or 2nd round, you'd probably have fallen to an A-. you really probably dropped much less than a whole third of a grade - your A is probably very good and your A+ was definitely very low.
