No 0 multipliers, everything can be tactically dm'd
Need scaling down perhaps, 9x is some big points, maybe 5x
Stuff like knees and elbows are good for blocking so damage multipliers are kinda weird, personally would leave them at 1
only things I would change are:
head 5x
chest 3x
abs, glutes and lumbar 2x
maybe shoulders and hips 2x, 1.5 would-be better if it's even possible otherwise meh
