Oh dear... another Skill Speed enthusiast.
Switch that around to STR > Acc to cap > Det > Crit >> SS, and then you'll be closer to making sense.
Must be some amazing testing if it concluded that Skill Speed, a stat that has absolutely no effect on Auto Attacks (which account for ~60% of where MNK DPS comes from) is the best to stack.
EDIT:
Brain fart with the 60%. It is actually more like 25%, which is still significant.
