Everything I've read in USTA documents or FAQs says they don't count at all towards year-end ratings. However, someone claiming to be a league coordinator addressed this and said they do count. See http://tt.tennis-warehouse.com/showthread.php?t=440721
So I don't know the real answer for sure, but I've always been of the opinion that they should count if they are "meaningful". Meaningful is when the expected result of the match was closer than 6-0,6-0.
I understand why you don't want to count them when say a 4.0 plays a 3.0 and the 4.0 is supposed to win by "more" than 6-0,6-0 so counting it would hurt the 4.0 and help the 3.0, but if two near equals play and one wins 6-0,6-0, why throw it out but not a 6-0,6-1 score?
FWIW, in calculating my Estimated Dynamic NTRP I do now include them if they are meaningful by the definition above.
