Just to maintain shuffle/agitation timing, if I have only one or two sheets, I add exposed, processed blank sheets so that I always have a minimum 4 pieces of film in the batch. I don't think I've ever processed only one or two sheets at a time.
And, just as aside, I too have had problems with interior camera reflections screwing up exposures. To deal with it, I did the same thing you described: painted surfaces flat black, and even had to put black felt on a surface in one of my Wisners to stop it from reflecting into the film in specific conditions.
From what I know about the chemistry of the film development process, I think the problem, most likely, occurs somewhere in the first minute in the developer, probably being linked to initial submersion and agitation. Still — I'm not sure how to successfully address the situation.
Thinking more about the issue last night, I decided to make a note of all sheets that include open sky and process them separately. I don't know that it will do any good, but at least I'll have a better baseline for comparison.
Thanks again, Scott — And any further thoughts will be greatly appreciated.
