Have the data cuts used in the analysis to extract target polarization
been looked at recently? The variations from left to right and from day
to day seem to be excessively large.

I rested them 45 minutes, filled, and trips resumed immediately. I rested them another 45 minutes, filled, and trips, again, resumed immediately. Now the guard wire trips are bouncing around from box to box... no sense can be made of this so we're turning them off until Doug arrives.

according to pol.log, the right sector measured/fitted values seem to fluctuate between 0.333 to 0.430
while the Left Sector values fluctuate between 0.319 and 0.667. Left Sector seems good for the optimists while right sector seems somewhat disregarded. Polarization is obviously up but we're still dragging behind last year's miracle. I also see a 20% decrease in thickness.
