Given the fact of the size of the wings built in a location far from assemble area, a smart and cost cutting company will be holding low stock levels.

Delivery times for the 787's wings, built in Japan, will be reduced from around 30 days to just over eight hours with the 747 LCF. from wikki.

Realistically anything over 30 days stock would be excessive.
I don't know on what date the spreadsheet was updated, nor do I know the author's sources, but believe him to have been publishing reasonably accurate 787 data for years.

Uresh, publishing at All Things 787
The lines of the spreadsheet of relevance to this discussion which show non-zero entries as of the update are:

11 Undergoing final Assembly
7 Pre-flight prep
16 production testing
5 ready for delivery

That does not cover the pipeline back before actual final assembly, but that pipeline is nothing like a few hours in length. (I used to work in a different line of high-tech manufacturing).
