Both MTP connectors got the treatment, so it isn't likely that
cleaning the alignment holes again would change things.  We'll have a
look.

The plots show that sp2 is loosing weight faster than sp1 even when
not connected (but at a far from alarming rate).  Bob, could you
check the dewars?  If it looks like there might be an issue, swap
dewar #5 (presumably on sp2).
