David: good to know that you're confident of the looseness of the process! I'll go with +25% for a first try (4:00) and see what the contrast looks like.
Given that currently these will be hybrid-processed, I'm sure that nearly any developing error (including crossover) is correctable. However, I don't want to soup a bunch of rolls only to discover in future that those ones can't be optically printed.
Edit: I just had a thought that should have been obvious an hour ago... it's all moot since I can just add a little more concentrate to bring it up to 1L of dev in that bottle. I can still run this one by the book! Of course that means I'll have about 1.5L of dev mixed up when I really wanted 0.5, but the 1L bottle I can squeeze to have zero air and there are reports of it keeping OK like that.
