The thing is, there isn't really a correct or incorrect. You just can't divide by zero. I was just thinking that Markus could make a "design decision" and make the k/bb blatantly high. If you saw a guy with a 99.9 ratio, you'd know what the case was.
I mean, if I have a guy who is having a phenomenal year and has struck out 40 and walked none, he should be leading the league in k/bb ratio. As it is, he'll be dead last.
