You might at least vaguely allude to the fact that some might not agree with this on the list. It's T Max 100 (TMX) which needs a stronger dilution. So they changed the literature in case other films turned out to be also the case. T Max 400 (TMY) is long proven by many people to work great with Xtol 1:3 which in a metal tank renders it @ 62.5 Xtol per roll. Way less than the 100 ml per roll now said to be necessary for straight white hair and yellow curly teeth!
