What am I missing here?

The definition of growth and attrition. Based on my earlier looks at these numbers*, I believe that "growth" has already had attrition subtracted, so that "growth" should be called "net growth".
Making the same assumptions as to the data source, the info up to about 2002 is not dependable because TBA does not include full event information for events through 2002, only those who received awards are reflected.
I also understand (from a Sean Lavery post, IIRC) that the 2005 dip is at least partly due to some missing event information from 2005.
* I'm presuming that this is based on the data from TBA re-posted
