on that note, does handling the officials from the townhouse count towards intellect? does trekking to the catacombs boost your strength/stamina?
does shopping for beauty-boxes give you an idea on how to improve your own looks?
basically, specific actions that replace your actions with the girls with in a certain amount of actions you can do per day/week (after all actions take time and time is finite within the length of a week) simply put: find an arbitrary amount of actions you can do before the week ends something like 40 or 50. sems reasonable to take that amount, not too few but not so many that you can keep tweaking the performance of every girl you own.
I realize this will turn this game into a turnbased one in one aspect but it does have advantages too. you can always make it so they don't HAVE to do anything but can scoot to next week by hitting "end week".
all in all, having actions define the growth/decline of your stats only needs a suggestion on types that fall into the credible ones, i'm sure we are all interested in a good addition to the game and we can see merits in other person's suggestions, it's simply how we react to those suggestions that make it positive or negative:)
