This "Stand development" option gsgary is using was initially developed to allow the photographer better control over his beer- and ale-drinking routines. It gives a guy (or gal) an adequate amount of time to actually drink some beer, and maybe have a snack with it, while developing film. No more of this constant-standing there-and-timing-everything-in 30-second-intervals...none of that nonsense..it's like pour it in, slam the tank down a couple times to knock off the air bubbles, agitate for a full minute (that's 60 whole seconds of your life right there!!!) , rap the tank real hard, then set it down, and then you've got like 30 full minutes to go and drink beer before you need to come back and slosh the tank around a bit!!! It's an awesome method!
