Yup there is, when playing there is a cap and someone explained it very well in page 105 of this thread.
56750 = 5600 + 5500 + 5400 + 5300 + 5200 + 5150 + 5050 + 5000 + 4950 + 4850 + 4750
being 5600 girl #1 all the way to 4750 for girl #11 for a combined level of 56750
I think that is what you are asking.
If instead you are talking about the stats of the girls with shares, that cap is at level 101 for each of the 3 stats
