And if we both use a Leica M5 with 35 mm or 50 mm Summicron at the same f-stop (aperture) we even minimize the "lens factor" as well.
I read about stand developing not so long ago, but don't know where anymore. I'm going to find that book first. Maybe it was The Edge Of Darkness (Barry Thornton) or The Negative (Ansel Adams) or The Film Developing Cookbook (Troop & Anchell) or Experimental Photography Workbook (Christina Z. Anderson)?

I'll let you know where what was said about stand developing. If you like, I can scan the pages and mail it to you (if so, send me a PM with your mail address).
About the salt, I have no experience with adding salt, but it seems to me it should be dissolved completely. I would heat water, add salt, let it dissolve and cool down and then add the right amount of (concentrated) salt water to the developer.
