RuneArm Charging and double X bow RoF?

[Kodwraith]

Does charging your runearm limit the rate of fire for the double xbow Inquisitor style?
It seems to based on dummy tests and it seems that having any charm on the arm halves the rate of fire, but I can't tell if it's just the animation that's messed up.

Just the animation.
It looks like you're holding the crossbow sideways with the rune arm, but it still shoots forwards.
