I have a comment on one point you made, " But the conception that the sliding window is causing certain coefficients to suddenly see the wrong values applied to them just doesn't hold up. The same data (ie, closing price, etc) will be input to these weights exactly the same way every iteration." I am starting to believe that there could be an error in the way the stock and related price arrays are fed into NS. That is, the starting and ending dates of the data may not be matched up properly. This is just speculation on my part, but it fits my observation that sometimes nets' scattergraphs go badly "out of tune" with the addition of just a few days data. Also, this may occur only if the data array contains more or less than the maximum allowed days of data, this could explain the difference in behavior I was seeing between the commercial and shareware versions, with their different max days allowed.
