A few comments on this:

* as far as I remember the pip count isn't used at all as input for
the neural nets

* if the pip count had indeed been an input we could have found the
expected change in the cubeless money equity by using 'eval' which
prints the derivative of the cubeless money equity. This is useful for
finding out the effect of changing a given input, i.e., 
delta equity ~= dE/dI * (delta input).
