I don't see any channeling in the puck but wouldn't the flow start later if going finer?
Do you have this same machine?
Where are you looking for channeling , with a naked pf as the extraction occurs or after the shot has done and looking at the puck after the OPV has hit. If the later , thus is telling you little about channeling ( IMHO )
