FWIW, I find it cumbersome to take a Zone V reading and then subtract two stops to find Zone III. See if you can find a Zone dial/sticker for your meter. There are some available for free download on Ralph Lambrecht's Darkroom site. A Zone dial will allow you to place the Zone III (or whatever) value and then easily see where the other values fall.

If not, I would set my meter's ISO two stops higher than the film is really rated so I could just point it at an important shadow and get a Zone III reading at least. You will then have to count stops to find where the other values fall, but you can do that on the fingers of one hand most of the time.

As for ic-racer's method of just using VC paper; if you choose to do this, I would advise that you standardize on a bit less development (i.e., less-contrasty negative and use the VC to build contrast. VC papers at low contrast (e.g., 00-1) have some evenness problems in the middle values (loss of separation at skin-tone value, etc.). These go away above about 2-2.5.

For me, I have development schemes that go from N-4 through N-2, although I too, use changes in paper contrast and figure that in when determining development.
