A problem exists with these settings. Your exposure will vary
considerably as you work with them to find the contrast you're
looking for. The Ilford data sheet lists these as well as
combination settings of both Y and M for each contrast level.

If you use the combination settings of both Y and M - your
exposures will remain relatively quite consistent.
