That's a typo. It should be November 2013. Thanks for bringing that to my attention.
The current production rate completion date is always variable depending on the current production rate. So you will always see this fluctuate. But not by that much!
This date is figured this way: If Sprint subcontractors continued to complete sites at the rate it has for the past 2-4 weeks, how long would it take to complete the market?
Since speed picked up a little in the LA Market, the date moved up to November 2013. If it slows down, the date will go further out. If it speeds up, then you will see this date move closer.
