Questions about Far Shot, Point Blank, and Kinetic Blast

I've recently been working on a Deadeye kinetic blast wander, and I was wondering about the interaction between Far Shot and the bubbles from KB. As far as I know the bubbles are considered projectiles (PoB scales their damage along with Point Blank, so I'm taking that as a fact), but is the point of origin the player or the point of impact of the KB projectile? I'm leaning towards believing that this would be the case, which leads me to question whether or not Point Blank could actually increase KB's long-distance clear, since most of the damage from the skill seems to be shotgunning bubbles. Any thoughts?
