Yes, I set the soft filter first then determined the hard filter. After I worked them up, I printed the two exposures in the opposite order and it didn't seem to be different.
BTW: I also took the advice of others, here, and tried printing with only one filter. I determined that a #3 filter came up with a result that's nearly the same as what I got with a #0/#5 split. I think I'm going to try a #3-1/2 single contrast print and compare to what I got with the split filter.
Overall, I think I have learned that I can do what I need with only one contrast filter unless I have the need to alter the contrast in just one area of the print. Even though it ended up taking more time to work up a split grade print only to end up doing a single contrast print, I think I have learned something that can be useful later on if I need it.
