Yes.  I guess I didn't look closely enough.

What I was really wondering was whether this can be expressed in terms 
of
known constants.  But I guess we don't have enough information to
determine that.

given the cited observation,

 "...the fraction of [1's, 2's, 3's, 4's] seems to converge, to about
[.287, .530, .179, .005]..."

that average should be the dot product of these vectors, i.e. 1.904
(well, modulo rounding errors making that these percentages add up to
more than 1...)
or am I wrong again ?
