GV7 sagged 
GV7 has sagged since John and I reinstated normal operational state this morning by re-applying 50-60 psi pressure upward on piston and removing locking pin. Not sure how far down it has sagged. I suggest waiting to run laser until it's boosted back up Tuesday morning by someone from the vacuum group.

3 hour trend of CS instrument air range between 62 psi - 82 psi.  

As found, 55 psi < GV5, GV6, GV8 < 60 psi, GV7 = 38 psi -> Adjusted all for > 60 psi. 

Note: the LVEA was quiet and I could easily hear the displaced air exiting the pneumatic manifold vent port.  I would guess that the gate had sagged several inches (foot?) based upon duration of audible venting and the convincing "THUNK" of it hitting the hard stops.
