smoktem, I'm not that good at scoring bucks, but I can't sort out more than 5 or 6" of extras there. Where do you see 13" of extras's? Just for a learning experience, it would be interesting to see exactly where our numbers come from.
I think his left side stickers give him 1 3/4" and 3 1/4" or so. All the other stuff is less than an inch IMHO.
Cheers,
Pete
