Quoted from ifpapinball:

Yup . . . it becomes "X+1" sets of drops to light your next mode, so IMO it's best to try and make your Prison progress BEFORE you start your first mode. Nothing worse then needing to complete 2 sets of drops to light your second mode when you're getting close to stacking a mode with a Multiball, BUT you're far more likely to bring in Blood Bath at that point assuming you were clearing your drop target banks efficiently. By the time you're lighting mode #2, you'll be through 3 sets of drop target banks, which should have Blood Bath ready to go on the next set (assuming you cleared through the Food, Supplies and First Aid efficiently). Huge risk/reward opportunities are around every turn.
