Thank you, Les. I'm going to keep working on this, but I think I'm off to a good start, and may add a little dodging and burning. I'll let you know if I have any trouble.

Yes, I do find that I have less burning and dodging to do. I think it's because the separate exposures, each at full settings, actually bring out all the shadow and highlight detail that's in the negative. That said, I still do use burning and dodging frequently, particularly when I have (1) a negative that's not as well-exposed or developed as it should be, and (2) when I want to make deliberate changes to the density or contrast in some part of the image for aesthetic reasons. With most well-exposed negs, the basic M and Y exposures will get you very close on the first try, once you've established your basic printing times for a specific paper.
I do always give full yellow and full magenta exposures. I can't say why your yellow exposures give you widely varying times from your magenta exposure. May be your colorhead or filtration system is different from mine. I have a Beseler Colorhead. Also, papers vary considerably in what their emulsions require. E.g. Ilford and Forte papers usually want about twice as much magenta as yellow. Agfa times are less widely separated.
My basic times for Agfa MCC, for example, are
at 8 X10 size print and f/11 lens setting: 8 sec. full magenta; 6 sec. full yellow.
at 11 X 14 at f/11: 12 sec M; 9 sec Y
Of course, this is to produce prints to my subjective taste in contrast and density. Your preferences may be different. I tend to like full information in shadows and highlights, so I tend not to go for a lot of stark blacks or stark whites.
You may wish to try this in conjunction with a divided developer formula as well. I have an article and formulas in the "Chemistry recipes">"Paper Developers" section if you're interested. I've also used this method of development exclusively for 25 years.
Thank you Larry, it's great to get advice from people with so much experience. I'm not ready to try the divided developer just yet... one thing at a time! But I think I may employ this technique a lot. It was really easy, and I think you are right about the exposure times. The last neg I printed I didn't do any exposure testing... time was running out, and I had to pick up the kids! Both the other negs I had printed came up with the same times, and that last neg was nearly perfect.
It's snowing today... no school, so I won't be able to try it again til next week!
