Yes, according to Bill Troop and others, the Ilford proposal was made as a stop-gap during a water shortage in Britain a few decades back, but Mason, of Ilford gave the math to show that the 'Ilford' method does not achieve true arhcival quality. I'm not going back to rehash the math again here. Suffice it to say, Mason has refuted that methodology and Ilford has never revised the method so there it stands.

What is worse is that there are several interpretations of the method going around that vary in detail, and this confuses the issue even more.
