I routinely used 7.5ml HC-110 syrup (US version) to develop TWO rolls of 135x36 films (Dil H in a 16oz SS tank), no problem at all. I read somewhere that 3ml is the minimal amount actually needed for one roll - yes I am well aware of the 6ml as the minimal requirement for one roll in most websites. I initially started from 15ml for two rolls (Dil B in a 16oz SS tank), then down to 12.5ml for two rolls (Dil D), 10ml (Dil E), and eventually 7.5ml (Dil H). My Tylenol measure cup has marks of 5ml, 7.5ml, 10ml, 12.5ml and 15ml. Perfect for my purpose.
So back to your question, I think anything beyond 18.75ml should be fine (3.75ml per roll based on my formula). I have a 32oz SS tank (4 rolls 35mm). I normally use 15oz syrup and Dil H.
