Query: Perturbative Subtraction Methods   The effects of an automated, tenth order in $\kappa$ subtraction scheme on
the noise variance of various Wilson QCD disconnected matrix elements are
examined. It is found that there is a dramatic reduction in the variance of the
lattice point-split electromagnetic currents and that this reduction persists
at small quark mass.
