Ice crash actual dps?

Hey folks, I have a question about ice crash.
currently it's showing me about 480k tooltip dps (fully buffed)

is that only the first explosion? or deal all 3 stages together the tooltip dps?

if not it would be 480+0,8*480+0,6*480=1152k dps right? (after a few attacks when its like..you attack and at the same time the 2nd and 3rd explosion of the hits before strike)

But that would be kinda insane right.

I realy think YES, I'm trying to make build for templar, based on cold damage and ice crush.

ING Magnument, Archesar

I'm doing pretty well with my setup so far...I just "recycled" my static striker and tested around with ice crush, reaching these amazing numbers.

I use Ice Crush+Concentrated+Melee Phys+Faster Attacks+Phys to light+WED with hatred and HoT (for Autocurse, HoA would be better)

dual Doryanis catalyst, lots of phys/wed/ele damage and life in the tree

i doubt the different stages can hit the same target even if its overlapping the radius of each stage.
