Almost forgot, there is another thing.
After winning if you use finales, there is less chance to see images of girls without finales. I think this affects replaced girls too. In fact, if you have 4 last-standing girls with finales active, I do not think I am even able to see images from replaced girls in rotation.
In my opinion, while images of girls with active finales should have a higher chance of appearing, I think currently it affects too much negatively other girls from appearing and especially replaced girls (if they appear at all, if multiple finales are activated).
