I, too, would like a better understanding.

I will be the first to admit that I am not the most exacting darkroom worker, but I use the same thermometer, tanks, reels, water, developer (distilled for developers!) and fixer all the time. I vary the time very little (5-10%) and am careful to clean all equipment immediately after use.

And yet I have seen some rolls with very pronounced stain, and others with just an overall, slight warm color. If I can't count on a significant stain, I might as well go back to a 'normal' developer.

Some rolls of the _same_ film or is this different film? Different films do vary a lot in the amount of stain produced.
Also, you probably already said which Pyro developer you are using but I missed it somehow. There are several alternative formulas which have proven to work in practice (and a lot of old ones that are probably of historical interest only).
I compiled a bunch of Pyro formulas for the literature which are posted at:

 These are mostly old stuff. No garantee on which work.
