That's what I have said all along....they indicate the first instance of product in a store (possibly), but there is never a withdrawal of numbers if not re-stocked or re-ordered. I highly doubt there is 100% retention.
There is possibly quite a bit of stock wastage too with Jerry's relatives and other unsavory characters working as distributors extracting their share out the back door. Distribution in every sense of the word. One case in twenty or 5% off the top sounds about right.
