The real value of split grade printing is the ability to dodge and burn INDIVIDUALLY at different filter grades, which helps you interpret the negative in nearly limitless ways.
You can't do that with a single contrast filter.

This whole split thing is a big waste of time and paper except for very specific prints like where you need to burn in highlights. For grade 2/3/4 you get the very same result with without split.
You can also print with normal contrast and do an overburn with #5 or 150 magenta to get better blacks.
Save yourself a lot of time.
