Printing on grade 4 (or 5, which would more properly called 4.5, at least for Ilford Multigrade; look at their published curves) leaves no room if I need to, e.g. burnin shadows at higher grade to give them punch.
You can increase print contrast by applying subproportional reducers after the process. This gives you plenty of room for experimentation and optimization without any risk to your negs.

I have made the observation that modern multigrade papers, assuming full development, don't respond much to changes in developer composition. Given that, I'm surprised you saw any difference at all.
Trying to be the best of whatever I am, even if what I am is no good.
