Timeframe for X6 build from start of production

[Low Note]

Since there may be some people in these forums who work for BMW or have a great deal of experience with the Greer plant, I would like to know if anyone out there can tell me how long it usually takes for an X6 to be completed once it enters code 150 (production started). According to my dealer, my 2010 X6 5.0 entered 150 status late last week. I tried to get more info from the website and phone hotline, but neither were of any help. Many thanks.
