Maybe the levels detection area should go into each level. So you can customize what causes the progress bar to progress at each level. For example level 1 shows boobs. Level 2 blocks boobs so boobs so in level 2 boobs no longer progresses the bar.
Edit: It seems like the Decreasing Progression Speed overpowers the Increasing progression no matter what number it's on. Even. 0.01 overpowers the increase if there's both a box that is supposed to increase the progression and decrease the progression at the same time.
