One 8 x 10 sheet = one 135 - 36 roll = one 120 roll.

So your 6 ml per roll of 120 makes sense.
Matt, I am glad I posted. I have always found that section of the data sheet a little confusing but what you say makes sense. At least I have not been using too little. But what about 4x5? This would mean each 4x5 sheet requires 1/4 as much, or only 1.5 ml per sheet! This is getting close to "development by faith alone." If that is the case, then it will have a big impact on just how much I have to load up the Jobo drums. This is good news.

On the other hand, it now seems like I have enough HC-110 to bequeath to my grandsons. I hope they don't just drink it.
