I can't really say anything about that, as I haven't tried Pyrocat-HD with stand development yet. The films I did with FX-2 seems to indicate that this may be so in that case too, but the films were different (FP4+ and TMX vs. PL100), and the camera/lens were different too (shutter sped may be different). FX-2 with normal development seems to give a slight speed increase (about 2/3 to 1 stop), which is what I'd expect.
My belief is that if there is a loss of film speed with stand development with either FX-2 or Pyrocat-HD the reason is development time was not long enough for the dilution used. In this case it is merely a question of getting the right combination of dilution and time of development. So if you are getting reduced film speed with eithe of these developers I would recommend that you either make the dilution slightly more energetic or increase development times.

The more critical issue is evenenss of development. That is the thing I am always most concerned about with stand development.
