This squares with what I'm seeing. Data for all holdings of the Orbis
Cascade Alliance is:

100: 30.1
245: 114.1
6XX: 36.1

My values include indicators (2 characters) as well as any delimiters but
not the tag number itself. I breaking up 6XX up as Roy has as 6XX's are far
from created equal and frequency of occurrence varies radically with tag.

I'm going to guess our 245 values are longer because we're an academic
consortium and holdings are biased towards academic titles which tend to be
longer.
