I've balanced the ITMY PUM/L2 coils using the demodulated optical lever method (LHO aLOGs 11392 and 9453).

I'll characterize in more detail later, but here're the results:
      Former          New          % Difference
UL   +0.973282       +0.971803     +0.15196%
LL   -1.01098        -1.01146      -0.047479%
UR   -0.98898        -0.988465      0.052074%
LR   +1.02728        +1.02881      -0.14894%

The encouraging news is that the balance hasn't changed much on the one QUAD suspension we didn't change. These new balance values have been accepted into the SDF system.
