Fruit of Grisaia: Auto-mode is super confusing

[voidpointer]

I can't figure out auto mode in Fruit of Grisaia. I jacked up the Auto-mode speed under Text section in settings but I haven't noticed it changing the delay between lines of text in 1x speed. How am I supposed to set this up? Why do the options not work? I don't like the 2x and 4x speeds since that also makes the text appear faster, and doesn't just affect the delay itself.

I remeber I've played with the slider set on pretty long delay and x8 mode. Is there a seperate text speed slider there? I don't think there's any secret/method to it, you just have to tweak it until you find the right balance (but yeah, I don't think x1 is ever useful, not sure how they came up with this system).
