Straight, as mixed from the formula. I mixed up a liter and had previously run about half a roll of film through it, so this was only the second time I'd used the developer. I'm not using a replenishment regime, so I figure I'll get about five rolls out of this liter and then toss (extending dev times by 5% over previous roll for rolls 3, 4, 5). I do think this could be a very good developer for replenishment.
As for my letting the film stand for one hour: the next time, I think I'd cut back to 45 minutes ONLY because the film base fog at one hour is just a little bit higher than when I ran my first roll with normal development technique. So I'm speculating that the one hour time brought up the base fog that extra bit, and that cutting back to 45 minutes might bring it down a little.
