Gah, sorry.
I'd started on a post, but got distracted and never finished. Oops. I'll go ahead and finish that.
In the meantime, Sam's total is 10,560 (440 for the Roomsweeper license, 2,200 for the burner SIN, and 7,920 for the rating 6 ID & license).
EDIT: While updating my Chummer file, I found that I already had a license for the Roomsweeper under Sam's original SIN; it just wasn't organized well, so I hadn't seen it before. So I don't need that, bringing my total down to 10,120.
