I'll use now the Microdol X and Ilford Pan F 50 Plus film combo for the first time and was looking for developing times and users opinions. The Ilford Pan F 50 Plus technical sheet suggests identical developing times for this film with Perceptol 1:1 and Microdol X 1:1 at 20ºC, 15' ; developing times have a very slight difference for both developers diluted 1:3, 17'and 18' and developing times for other Ilford films using these two developers are consistently similar or identical according the case, I think these are indications in the direction you mentioned above. The same technical sheet suggests solution B as the only option to develop the Pan F 50 with HC 110 developer, however the developing time is short too much: 4'. I had no good experiences using short times due to uneven developing; the Rodinal Special developer (nothing to do with the true Rodinal) was very active having short times, it was good for photojournalism work but it's not so good for others works. The page quoted yesterday about the HC 110 suggests:" The solution? Try the unofficial dilution H which is half of dilution B, and simply develop twice as long as for dilution B", perhaps it works.
