The bad news is that although varying strength of solution makes different
contrasts (as does double coating), varying PROPORTIONS of A&B changes
results according to who you are & why, also your paper & which formula.
Really -- my students and I and didn't get results always consistent with
each other and/or Bob Schramm: it's worth a few tests for a particular
problem, but choice of paper may be easier.
