I modified the rails (per RKC specs) and installed Artemis cushions on my red labeled
Diamond Professional, bringing it up to the blue label specs. Cloth is Simonis 760.
50x100 = 1.00 TSF, 4 1/2 = 1.00 PSF, 5/8 = 1.02 PAF, 1 3/4 = 1.03 PLF = 1.05 TDF
All measurements done in Autocad, at 1 to 1 scale. Measuring on the table was too difficult.
Very nice! Yes, as some of us have been saying all along, measuring the table itself is "fraught with peril". I had to redo mine as explained below. IMO both your photo and your method of measurement should be included on Dr. Dave's resource page as a guide to accurately measuring pockets. FWIW I think you should also consider using the software to show the actual facing angle, and/or show a measurement of the cushion width.
After Cigar Dave mentioned that his cushions are 2 1/8" wide (which is 1/8" wider than "typical"), I got to thinking that I hadn't bothered with mine when I reported my measurements. Turns out they are only 1 7/8" wide. This explains why I got an actual facing angle of 144º when measured very carefully with a sliding bevel and protractor, when in theory I should only have an angle of 143º with the 1" difference between mouth and throat measurements.
I took some masking tape and extended the lines of the facing. Then I placed pieces 1/8" (eyeballed only) outside the seam between the rail and the cloth. You can see in the photo that the distance measured across the intersections of these two new sets of lines is really 3 7/8" instead of the 4" I reported earlier. This is a 1 1/8" difference, or 9º more open than 135º, which comes out to the same 144º that I measured with the bevel and protractor.
In other words, the difference between pocket mouth and throat measurements is absolutely meaningless unless it can somehow accurately provide the actual facing angles that are of interest for determining the PAF.
