Your formula is incorrect, your black bile doesn't matter for pistol damage. Your damage output would be the same with 10 black bile. Back in the days yellow bile had influence on your gun/pistol damage, it now is percentage based as a catch up mechanic. Your common combat power also has a small influence on your damage output, but you would need alot power in order to feel a significant difference.
It's damage to animals not players - read it again - beaver is an animal.
How on earth I could 1shot beaver if pistol damages for 15% ??
Damage to animals is not % based since patch 1.2 and BB based.
Experienced player like yourself should know it.

@Kandarim I don't claim its accurate i was hoping someone will bring more data and then construct the actual curve - what I didn't wanted was a worthless comment.
My bet is the actual curve is a gaussian.
Thanks for help.
