ABSTRACT.     Certain approximations for the spin expectations have been
studied both numerically and theoretically. Approximations are
constructed using solutions of the lattice heat equation. The
most interesting idea is a certain randomness assumption for
a theoretically derived quantity, that leads directly to a
given approximation. We are betting the randomness assumption
is rigorously correct.
