0.5 is about all I'd give it. Once in a while I might get tagged on a knuckle or get a papercut type wound right on the cuticle and it stings. Half the time I have to wait to see if there's blood to see if I can count it as a bite or not. Baby BPs are hysterical when they try to kill you. They look so serious about it.
Now.. the blackthroat monitors I've avoided getting bitten by.. I like keeping all ten fingers.
