Yes you are correct about the typo for Grant Haist. The monobath Manual is a great book and while fairly slim summarized monobath development at the time of publication. AFAIK, interest in monobaths soon faded after publication because of the difficulty in a producing a bath which would work with any film.
I was commenting on Ole's post in which he says "... I've turned to "two-bath monobaths" - single shot developer, pour in a dash of rapid fixer concentrate at the end of development." While this may work it is not a monobath and will not produce the same results as a monobath.
