Corey and I shot levels with the Sokkia Optical Auto level.

Attached is my logbook page.

Bottom line, the top of the Stage0, at the Alignment/Assembly Posts is level <.2mrad and,

the Optical Table is level to 1/8mrad as well.  The level requirement given to me by IAS (Doug & Jason) is 0.4mrad so we are comfortably under that.  So no fussing with the MTS with the ISI on top.
