I should check on those, but I think I can sub-1 most of them.
I was really impressed with myself the other day when I actually sub-1'd one of the N-perms. I didn't think I had it in me. It's definitely not consistent, but it was definitely sub-1. I think it was N(a), the one more similar to regular J-perm (not "L"-perm), and I think it was a 0.97. I got that time at least twice.
My N(b) perm isn't nearly as fast, but it's definitely more consistent. My best is around 1.13, I think. Not sure. Don't quote me on that.
