I basically did the same thing a couple of years ago with all of the various vintages and grades of Azo I have on hand. I used a 21 step tablet (instead of a negative) and the same exposure and processing for all except the last batch of #2 which I processed for 2 minutes instead of one. I put a number on each box of paper and it matches a number on the print. Not a subtle as using a negative but it lets me get close in exposure when trying a different paper by giving me a relative speed/contrast for each paper plus it was easy to see what boxes were pretty much the same.
