Leaving girls out for filming or training kills them off and they haunt your OCD.
Ok, seriously, I do not know of any effect with resets. You do not get any bonus. Aside from maybe speeding the outfit event up. by sending girls to film before resetting.
The digits will shorten to 1k I bet. They dont do nice numbers. Everywhere rounded numbers, even the total bonus is rounded. Any number too long is written with less digits and symbols and rounded if necessary. Example is fake it costs. In the button to buy directly is has 5 digits a point and a symbol. In the button for scene completion it is shorter. My current total bonus is displayed rounded up near the alarm clock and in the reset menue it is with decimal point.
There currently are 160 different positions on 17 girls to film. Getting to 40+ takes a long time. 40*160=6400.
I assume Victoria, and she has 11 positions and you know how long it took you to film your best girl and neglecting other girls (filming them in lower studios or not at all) so you should be mid-40 with the positions.
