To continue with the technical discussion, Mark, you mention that development times are longer for this formula than XTOL. I see above where you say the time multiplier for TMY is 2.19. Do you have a general idea where we might start with development for a given film (say HP5 or Fomapan 100) based on XTOL? Do you think 2.2 might be a good number? I'm sure it will vary somewhat for each individual film. Just looking for general guidance.
