I'm with Greg. Don't overthink it - just go out and learn what the car wants. Listen, and it'll tell you what it likes. Though it may take sleeping on it for a couple of nights to put it all together.

Last time I made that first transition from a soft to a stiff setup (this on the same car), I spent a whole weekend driving straight into curbs. Wasn't till I had time to sleep on it that I realized, after the race weekend, that I was turning in at the same point; I just didn't have to wait 2 seconds for the car to respond! LOL You may very well have a similar experience...
