^ I don't understand ANY of this discussion at all. Really?
The OP complains of soft tissue pressure BETWEEN the supporting points of his pelvic bone(s). That means that it's not the pitch angle of the saddle, but the CROWN or CROSS-SECTION of the saddle between where the pelvis is supported. That's where the interference is. Too much contact where it's not needed at all.
So, OP, why don't you post a photo of the saddle that you're riding? I going to offer a blind guess that in cross-section at the seat area, it's bowed downward toward the sides or crowned. Also, it's likely that you have one that has gel padding or some such, so is too thick and/or soft. This spreads out the contact pressure, which you don't want.
You want a concave saddle, one with a pronounced channel that cannot give pressure. The sit points should be firm and flat, and as narrow as needed to support your pelvis at the tilt angle(s) where you will ride. Your fitter should have already explained this to you. A better anatomical saddle would be advisable.
Look at Kontact saddles, for example.
