Also, the writer says you killed 5 men. One of them was the unarmed bar tender, so if he's counting him I guess the count is correct. The writer also says "When confronted by superior numbers an experienced gunfighter will always fire on the best shot first." but William shot the unarmed bartender first.
And when shooting Little Bill the second time William's rifle makes 4 sounds (back, forth, something, & something else) when being cocked, but when he kills the second guy on the way out there is no cocking, and before he says he's coming out it makes 3 sounds (back, forth, & something)
