Actually, you can't ever trust the WBTS stats. They never have and never will present the actual numbers. I knew somebody in the Service Department who confirmed this, and to them it wasn't a bad thing...it's just how they report!
For one, publishing hours are now deluded with RBC work probably up to 50% of the numbers reported, (to the delight of many in the hall). That is just the obvious one everybody knows about.
