Annex N is for the shop, it's the forms that may be used to create a WPS. You don't HAVE to use that version of the form, but it's a good starting point.
Section 7, that's what I did, once we got the machine dialed in, and did 10 studs in a row, visually inspected the "flash" and bent them all, I used that to create my WPS. The code is vague on what method to use to bend them, I use a pipe about 5' long, a nice even consistant effort and don't put it all the way down the stud, I left it up about 1-2".
If you do a search for stud testing, we all had this discussion about 6-8 months ago, and ther's some pictures of other guys "method" of consistant testing, that will help you as well.
See the "search" link up at the top of this block? click on that and type in what you are searching for and hit enter.
Good Luck.
