The problem is that the mechanics of this game are janky and the game is bad at communicating to the player what is exactly going on. What you have to understand is that the game is going to give you trash models to begin with. This means that while you can turn cheats on and try to see if you get lucky in any aspects of the models like their willingness to cooperate or if they have actually fuckable holes, you're best bet is figure out a quick routine so you can rate the models as fast as possible to progress the time. The more you do this the better the models will be to your liking, and then you'll be able to do more each time if you're rating them properly.
but thats where the game also suck donkey ass.
first off you cannot simply NOT rate specific things. if you leave something at 0 the game will think you absolutely hate it.
then comes the problem where you rated something with a 2 for example and the feature you rated just repeats for the next dozen models without a change.
and then you have those soft skill ratings that are impossible to do. e.g. you rate her according to her anger. and what you have tested looked fine for ya, so you rate her positively. but boi oh boi are you fucked if you forgot her frigging ankle, armpit or whatever where she suddenly goes absolutely mad nuts. and suddenly the game thinks: oh you like em going angry at ya! let me introduce some more karens to you.
ugh...
that frigging system is just so trash.
