David: The film speed test is only the beginning if you want to be rigorous. You need personal developing time and contrast evaluation. Also. it is really valid only for sheet film, as it is more difficult to control +/- development, which by the way is almost needless now that good MC papers are availble.(posted 8425 days ago)All this work was done when the only paper was a grade 2 and all negs had to be tailored to print on that paper.
Try getting a copy of Fred Picker's "Zone VI Workshop", as it has all the detailed instructions along with smple of everything. He is a bit quirky IMHO but he is technically correct with all the sensitometry stuff.
Cheers
