By default, we set to the nominal value from
the Turner energy rules and formerly from the original application of
the JS model where . When , this is exactly
the same equation as the JS exapression. Deviating from that value is
certainly not a crime, but with a little thought, one might realize
that the effect from this contribution would be mainly to *weight*
the entropy less or more depending on whether or
respectively. The contribution from the second term
in () is a constant, and the third term is usually
neglectable for these problems (**but not all problems**). In many
cases therefore, the result does not change dramatically when this
parameter is changed.

In short, if you really desire to know what will happen, you are free, but consider also that that is why you are lost. Limits have been set such that , where values in the middle seem the most sensable.
