280 pdps 1.9 aps 9crit ambusher with crit multi and spell damage

Crafted this pre-masters. For CoE users the pDPS is either 317.6 with the added spell damage modifier factored in as additive to %increased phys, or 364 if it's multiplicative i.e. 280dps * 1.3. Would appreciate if someone could explain which.

I used http://poe.trade/search/womamadokonaka to look for similiar daggers. I don't know how to price it since it has the spell damage, crit multi, and T1 crit but lower up front pDPS. I'm confident that my dagger is preferably to all the multi-mod daggers though!

From reading: http://pathofexile.gamepedia.com/Hit_Damage_Calculation

My understanding is that for CoE users the pDPS is multiplicative (i.e. applies to the local weapon dps) and thus would net 364 pDPS.
