Maybe but the towel you use is going to alter it. Plus you're stretching neoprene. No guarantee that the measurement will yield correct results. It may take several pieces of cardboard anyway if you're trying to stretch a 7 mil or stiff 5. I have gotten good results doing it the way I described on a dozen or so suits. As have others who have used the method. No need to overthink it. Cardboard is cheap.
I use the former ones and when on they stay more or less flat. In the water who cares because you'll have stuff in them so they won't be flat. I also want pockets that open and expand easily. Ones that are held flat by some mechanism may restrict my ability to get stuff in and out of them.
