All color heads, even same model of same brand, are different, and you don't need to match the filtration against a set of filters, you need to match the filtration against the paper's ISO R.
Start with the recommended filtration for all grades and using a stouffer determine the ISO R, then you will know if you need more or less for each grade. The idea is matching against a evenly distributed contrast range, not against what comes up from the filters.
Talking from memory, on 21 steps tablets each step is half stop. There are 30 R units per stop so ISO R will be dmax-dmin x 15 (numbers on tablet). Is not super-precise but it will put you on track quickly and you can refine later. The key is having a pure white in the strip. If you have a densitometer choose 0,04logD for dmin, proof for dmax and use 90% of it as dmax. I should say again that I'm talking from memory, so check for the right figures on available literature.
