Has it been discovered yet what the flank accuracy requirements are for the different coil turns and ex primals c.c?

I got my Allagan Spear last night and Maiming Bracelets so I'm trying to push out any damage I can with them so if I can drop some accuracy I'll happily do it.

Currently working with 472 on 1-4 and 482 (483 due to gear) on 5, but I'm seeing talk of dropping lower now?
