Sine I only very rarely pump affection of a girl for other occassions than the quest, I still have a very very good pool of girls who have yet to get over 10% (since I disike them on being on 0 all of them are upped to 2% and after that, the girls with higher priority are raised even more.) If a new 6* is present she will be maxed out as soon as possible - within the limits of the daily quest though.
