Chris, both in volume and or by solution strength; equal molar solutions. A
trick I learned many many years back was altering the ratio to slightly
change contrast in a print. 


Be careful not to the print rub on the bottom of rough tray, it should allow
the excess to fall off the print downward into the solution instead of
across the paper and onto some what active excess coating area that was
excited a little during the exposure looking for something to do with the
energy. It does not take long, or has not in my experience. It can also
change as the developer ages.

BOB,
Mine, too, occurred during the early part of development.  The solution
would stream out of the dark areas of the print.

Eric, you say check balance of pt/pd mix.  I am assuming you mean make sure
enough ferric, correct?  What I found is my eyedropper for pt/pd solution
was bigger than my one for ferric, hence I was getting more pt/pd salts than
ferric.  I corrected that as one of the measures. Is this what you are
saying?
