MSD digital E curve dizzy setup questions?

So the way this distributor is set up is weird. The directions are confusing the way to set up the advance curve. I wasn't sure if someone else had any input on the settings. I set it up on start lockout which is roughly 15 degrees initial but am confused on how to adjust the pots. Do you time it at total degrees advanced at idle then the processor takes timing out or what? Not real clear so any help is much appreciated.
