~1hr run, No GP adjustments needed

xD called for a radiator change and dumplett in, so we tripped beam to accommodate.

FIG.1,2
I've been trying to pin down why/how NL GP has not been slipping. ~1hr run with no adjustments to either North or South GP and the 1A spot has remained mostly intact. So far I haven't pinned down why the slippage has become less aggressive.
