Amrit, 

I have already talked to Bob and have asked him how the process would take. He could not give me an answer on that, but Dave has (as of today) started looking into the calculations. As for Dave, I left him a message and asked to meet with him to talk about a time frame needed to complete this. 

As for our end, I have collected the ODH document so we can assist with writing the OSP, and of course I already reviewed the submitted OSP and have the notes on what needs to be moved around so it makes sense.

marc joe's email went to everyone! 
everyone has already got the message. 
so, who are you forwarding this email to? 

you are forwarding a e-mail that everyone has already got? 
we have a pressure system calculation which was supposedly done which really is not done and no one has got it. 
we believe that dave is looking at it, however he has not confirmed it. 
today i found voltage taps (VT17 and VT 16) on the epics screens which are repeats, which begs the question why not name all the taps vt 2.5? 

i'm getting totally lost. 
this is really kafkaesque. 
please, go see in person, dave and bob, and explain what happened. 
given their schedule on the magnet they may not yet have had the time to go through all these e-mails 
i'm confident they'll sort it out
