I'm having trouble computing the width of a longtable and using it later in the table. This site offers several suggestions and I have implemented one of them. However, because of scope, or because of some of the nuances of longtable, the \global\advance\variable trick isn't working properly.
Below is my current output. The NOTES are supposed to extend to the last column.
Here is the code that produces the figure above. I realize that there are several tricks to get more sophisticated with the use of newenvironment and newcolumntype, but for purposes of debugging, I got close to bare metal. A previous question and answer on this side helped clean up the table and the command \rulefiller is a result of this.

What am I missing? I believe that scoping is handled properly with the \global variable. My only guess is that the longtable environment isn't processing in a manner that works with the \newsavebox and \advance tricks.
