She channels the dust through her weapon to cast all that though; I don't think we've ever actually seen Weiss cast Dust spells without a medium before.

So by that definition she would be at 2, because she uses a medium to cast her spells (her weapon being the medium). Cinder is a 5 because she can use dust in its raw form without a medium to direct her focus, and manipulate it into what she wants (such as when she fought Runy in DDI and created her bow from pure dust stored in vials).
