I didn't say the isoelectric point/pH had anything to do with gelatin swell. The discussion in Haist regarding the isoelectric point has to do with the affinity for thiosulfate and silver thiosulfate complexes.

Swell is discussed from a diffusion perspective.

With respect to The Film Developing Cookbook, it is a good book. I never said it was no good. But I can't agree everything they say about developers and fixers (developers in particular) is necessarily sound.
