I haven't tried mixing Xtol at a high temperature but did reverse the
order of the ingredients without ill effects on the film. My guess
would be that the temperature of the solution at the time of
developing is much more critical than the temperature at the time of
mixing.
Obligatory Leica item: I'm still on the quest for a decent 50
Summitar and a 90 Elmar with serial numbers between 633000 and
647000. Email me privately if you're looking to dispose of one of
these fossils.
