+Starred variances are underestimates, as the convolved variance maps do not have NAN values where data is missing, but rather have 0.0.  This data is therefore not excluded correctly in my statistics.  In any case, it appears that the convolution process has introduced the large discrepancy in the variances.  The following images show the convolved images and variance, along with the fake - convolved difference images produced by ppStack.  The diff frames highlight the fact that the scaling is incredibly far off from the optimum value.
