There's way's to test the speed matching (i.e., the ability to change contrast filters and still use the same printing exposure time) claims made by manufacturers. If you care to take it that far, then I would suggest Steve Anchell's The Variable Contrast Printing Manual; I believe all you'll need is a 21-step density tablet. There's also a good section in there about split grade printing; single filter printing, and multiple filter printing.
