You should be able to see the difference between the girls if you coach the new girl again. You can coach a girl again, can you?

Now my question is, are clothing items considered to decide which girl is best? And are the stats weighted or just added together?
It really looks like they just add the base stats to get your best girl. And I believe that what gets added from coaching is related to the ratios of base stats of the best girl. I have a couple that ended up with individual stats higher than the best girl. It may be that they matched the sum of the base stat and that I didn't see that since I continued to train the best girl for the days the coaching went on. It looks like you need to have each of the best girl's stats higher than another girl's to be able to coach her. My practice runs a full day, so it may be a while before I can test that.
