I added it. It was based on personal experience. If you get priscilla's dagger and go to town on the stray demon, it most certainly does not take off 50% of its HP bar when you bleed it out.

It is very difficult to test this on enemies as most enemies die before bleed kicks in, or is sufficiently damaged by that point to die regardless of how much the maximum bleed was. Maybe if you take an unupgraded bandit's knife and tested it on a balder knight in NG++++++, we might have tangible testing results...

Various players on youtube have stated the same thing, including ENB I believe. I don't know if there's an official source.
