Rolfe about half the people on this list use Xtol at way below the
recommended Kodak daily requirements we went thought this two weeks ago
and it's still a big issue you choose to rudely ignore. 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!
