Dose Rating Buster take into account 2hand'd vs 1handed+Offhand?

[Jynks]

I was woundering .. I use a mod called Rating Buster... I think it is a must have personally... anyway.. I always get confused... Say I am a caster...

If I have a 2 handed Staff and a 1 handed spellblade + a offhand... and the spell and offhand equiped.. dose the rating buster take that into account in the tool tip when I mouse over the staff in my bag?

Thanks in advance.
