Unscalable phys dmg question (e.g. h of blood, blood hunt)

So tooltip says it is physical hit dmg.

Question 1) Does it contribute to ailment power? E.g. I use blood hunt to apply poison (cannot cause bleed, but poison, what a power in mixed poison/bleed build). Even if unscalable damage part does not contribute to base ailment dmg, the skill attack damage is powerfull enough.

Question 2)
Does this unscalable damage contribute to leeching?
