Christopher: you don't say how you are developing (open tray, tank, taco, etc.,) or whether you are developing sheet or roll film, but be forewarned and alert: I have developed 4x5 film semi-stand and with minimal agitation in both Pyrocat and Obsidian Aqua. I used daylight tanks (film in a vertical orientation) until I began observing streaking, mottling, and other evidence of uneven development. I tried everything that I could think of (more vigorous agitation, extremely gentle agitation, more frequent, less frequent agitation, even vibration, and could not solve the problem. I finally bought a slosher tray and began developing in open trays and my problem went away. So if you are using sheet film my advice is to develop some sheets exposed on an evenly illuminated white or gray card, or blue sky, and look at your contact sheets carefully.
