I like to use the regular tie off holes whenever possible. Your rackets normal tie off at the head is 5H. So I suggested (because you have fixed clamps) skinning the fourth main on the short side and stringing the fifth. Ten after string the fourth you can tie off the short side at 5H.
I would normally string the outside strings in a box pattern to eliminate overlaps on the outside but you have a glide bar machine that makes transitioning from mains to cross a big more difficult so I did three on a side three at the top etc...
If stringing an 18 main racket instead of a 16 main one you should do 12 center mains instead of 10. This makes the pattern around the outside string work.
Everyone has the right to be stupid... it's just that some people abuse the privilege
