Yes, and Sandy's latest version of Pyrocat (Pyrocat P) was designed to give maximimum acutance with continuous rotational agitation. Lots of Apug posts on this subject.
Kev, the best method for outstanding contrast and sharpness is still with minimal agitation or stand development and pyrocat. Use the drum for your tests, but keep in mind that minimal agitation will open up a whole new world. Please don't limit yourself to the drum! tim
