The Pyro I buy is from Zone Imaging, I tend to follow their advice and use Rudiger Hartung method which they give the dev times on the data sheet which can be found here, essentially it's just a brief agitation every 7ish mins and around 25 min dev times depending on film stock, water as a stop bath and a neutral fixer.
In my experience it has been worth figuring it out, I'm finding a lot more detail in the shadow areas and very low grain, although, the negatives are quite contrasty.
pls do tell
