Considering your number of HP, and unless a special VIT meld, I would think that you are ilvl 120+. I find the damages you make on the dummy quite low... From experience, just wih virus/aero/earthII, i'll usually strike at 800 / 1100+ in crit, and far more often that what I see on the video. That said, i'm "only" ilvl 116. It's curious that you don't do more damage. For the record, my gear isn't exactly crit/det emphasized, more PIE and SS.
