I think I got 11 rolls out of it, simply because that's all I had at the time. I batched and did it all over 1 weekend. I know by the end the chems were starting to smell a bit rank, so I decided not to keep the solutions (+ I knew it was going to be a few months before I was going to shoot colour again). I can understand how it may be a bit of a stretch - I suppose you have to make that decision for yourself!
