Thanks so much for the clarifications.
I think I am getting it. So since you print Pt/Pd and that is the direction I am ultimately heading a normal SBR is 7ish.
An incident reading that gives an SBR of 8 means I develope normally or maybe n-1
If My spot metering comes out at an SBR of 2.3 i need to just take the camera to another location because I would be looking at N+4.7 development or am I getting this wrong too? Ugh.
Once I get over this hurdle I think I am ready to go. It might also explain the negatives I have been getting. When I apply what I thought I had learned from BTZS the negs were dense as hell and flat. When I applied the Zone system modified to look for a 7 stop difference I got good looking stuff.
