I was with you most of the way before my brain numbed with calculations, but the bottom line question I have about the Jobo drums is, can they be considered economical if they require reuse of the solution in order to meet the minimum capacity? Is it a good economy with good reliable and consistent results, or is it a bad econony with savings coming at the expense of consistency? I was never satisfied with results when partially reusing Ilfochrome chemicals, although it suited others. And that's my only experience in reuse of color chemicals, so I'm wary of total reuse. .
Although I'd like to do more than 4 sheets, Kilgallb's 90 ml per 4 sheets @ one shot use is much more attractive to me right now, assuming that gives me results I like.
