Actually it does. People who have a NuB have no control that their 6 months take place during a time they can't get extra exp. Also, if you want to run a competitive NcB then your going to have to wait till these two holidays don't take place during it.
Well then us N*Bers are getting shortchanged about 5362 (I did some rounding) mpr if we hit all of our BA verses some one who hits all of their BA in the first half of the year, while both shooting for 5 mil mpr at this very moment.
Maybe a cause for concern for some...but I am not too worried about it :)
