Geographical distribution doesn't really have a bearing on the weight of a Mss. After all, only 1 Ms can be distributed in 1 place, so it that is not really a distribution at all. Now if we were weighing readings of 1 Ms, and we observe that a reading is distributed in many different locales, then that would be something.
Indeed you are correct, and I was mixing my thoughts about weighting of manuscripts and weighting of
readings in my post above, which isn't very sensible.
So...to answer the question asked; I would say age of manuscript would be most important single determinant of its TC "weight", though by no means a conclusive one, since "young" manuscripts can obviously contain ancient readings, and very old manuscripts can (and do) obviously preserve errors.
Internal coherence of readings, or "quality" of readings,
a la Hort, would be next in importance, though again, even a consistent tendency toward excellent readings wouldn't guarantee correctness of all in any given manuscript.
Parenthetically, but still marginally on-topic regarding "geography", I despise the dishonest, question-begging KJVO-type arguments about manuscripts from Byzantium/Antioch being "holier", more "ordained of God", as it were, than those from Alexandria (which, being in Egypt, was of course an "evil empire" of sorts), nor incidentally do I put much stock in the local circumstances in which a manuscript was
modernly discovered being an indicator of its value. (Again, KJVO types love to try to make hay with Tischendorf's discovery of the leaves of Codex
Aleph at St. Catherine's at Sinai being in a basket of papers consigned for use as kindling, as though ignorance on the part of the monks there was a sign of the manuscript's being "garbage"!)
Such superficial and tendentious handling of the
facts surrounding NTTC evidence is typical of KJVO types, but unworthy of genuine scholarship, and is obviously
eschewed among honest people.
