PIC while doing dual...?

With the exception of safety-pilot time-building, wouldn't you just subtract your post PPL dual-received from your total PIC to get the 1.1 PIC number? Am I thinking correctly that that gets you to the same number?.
Only if you are never PIC on dual flights.

I have been PIC on flights when I have received instruction and I have not been PIC on flights when I have given instruction.
As long as the CFI gets to log all time when acting as an instructor, all is well.
