As SUS completed the ~6mm shift North yesterday, our turn to hoist the ITMx to height.  IAS logged that the ITMx need to be lifted by 3.6mm; however on 24 Oct I observed the Optical Table to be just 1.8mm low.  So I split the difference and lifted the system 2.7mm.  All went smoothly with low SD of the DI readings and very little off axis movement.  We'll see what IAS says next.  I was not able to evaluate the level of the table.  We'll do that when we do next tweeks and personnel are available.
