As a one shot process this really isnt a problem, its the Dev that goes quickly and that is the one to watch.
That's the reason I use the liquid kits. I mix what I'm going to need for a session and use it one shot. I only use this for sheet films (plenty of places to get 35mm and 120 souped) and my mix quantities are small.
