Well, if the event turns out to be: Film your girl 7 times to get an outfit, it would be rather boring. They could have given a chance or something to make it interessting, but this?
As the filming event is presented it would not make much sense to allow extreme values like 1,1,1. But we will see. Maybe a better guess would be 150+-50.
My first impulse was to guess by the color of the outfit in relation to the color of the sliders
If you purchase the diamond film studios do you keep them when you reset?
On my first few resets I thought, the filming locations had to be bought in order. Also, they could have just been unlocked by the diamonds to be subsequently be bought with money like the others. Just as many people wondered, if they would be locked again after a reset. After all, you can bu one-shot options for high amount of diamonds, like money, time travel or resets.
More studios get you more stamina. But it slows down, the higher you are. And the exp per training slows down too, the higher the stamina of the girl is.
Funny thing is, the game actually gets it right with the +700%. But it would probably be better if they wrote x8 to avoid confusion.
