Other than a CAS # and synthesis for the desensitizer,
I am not so sure there is that much mystery.

I wouldn't expect the Professor Dr. to know those things from a simple study.

More interesting is the question of how the developer behaves without it...
Is there any evidence of problems with the simple rodinal formulas?

I don't see the sense of trying to duplicate one particular formula if other,
similar formulas work just as well.
