Sounds reasonable - but the 2013 league does have some 2012 play in there also. Goober also brings up a good point, which is that many early start ratings are adjusted at year end. Whether this adjustment is only done by USTA to take into account benchmarking, nationals, etc. or whether it also includes dynamic rating changes from matches played after early start ratings, but before year end ratings, is the question.
I did look on USTA's national site and found some Q & A regarding this which said that whether early start league results count towards the same year's computer ratings is determined by the section league coordinator. Maybe no one really knows when the exact cutoff is except USTA.
