Mr Blank speaks the truth!
I have a color analyzer and don't use it. I've found that it is only good
for getting "close" to correct. (Although it does a good job for B&W
exposure!). You absolutely must get the density right (light/dark) first
before you can get out your viewing filters and adjust the color.
I like to cut a full sheet down (16x20 gives 8 test sheets) and pick the
most important part of the photo. I make three or four exposures on the test
sheet, run it thru the roller transport processor, then, if there is a strip
with good density, adjust the color.
I keep a Sharpie brand marker and mark the test print with the filters and
exposure. Sometimes, by the end of the night, things get a bit stressed and
it helps to write down what you're doing. My test print will be marked as
such: "40M 60Y f/8 :15--> 45M 60Y f/8 :18" This marking means that I am
going to add 5M and three seconds exposure.
Having a ring-around hanging on the wall is also helpful. I made my own, but
there is a ring-around in my Kodak Color Darkroom Dataguide from the 1970's.

As for the initial problem of prints from differnet films, I haven't noticed
a problem. I just make my test strip and go from there.
