I took a printing workshop with Les McLean last spring, and I really find that split filter (#0 & #5) printing gives tons of control. There was something Les said that no one has mentioned so far... 'a little bit of #0 goes a long way' or something to that effect. That's why I don't really think you can say "25% of the total time or 50% of the total time is one filter or another. I really think it's totally dependent on the negative. I really think you need to make the test strips for each negative to see.... if you try to put it 'in a box', it just limits your scope of the situation... IMVHO.
That was the rationale behind my posting. It works whatever timing system you use for darkroom exposure.
