The ASA ratings and development times published by anyone are "best averages".
Each camera has a different amount of flare (internal light reflection) which
affects the published "average".  Deriving a different ASA and development
time should be EXPECTED for EACH different camera, and for each LENS put onto
that camera if you are a hair splitter (different lenses will allow light to
escape into the camera body at different angles, affecting the amount of flare
inside the black box area).

I only say this so that no one expects his own situation to be exactly like
the experience of others.  The zone system, as detailed by Ansel Adams in all
five of his major books on the mechanics of photography, is fertile enough
territory for anyone who is interested to study and practice for years without
exhausting all of its nuances.  There also are some very practical and easy
ways to utilize pieces of the "zone system" to improve any individual's photo-
graphic mechanics during his learning processes.  Just reading the books will
probably allow anyone to improve from his current level.  Most of all, photo-
graphy is fun.  Enjoy it while improving your mechanical skills gradiently and
don't forget to improve also your artistic values of content and composition.
