Since I was asked…

...by more than one person.

Bill James once said don’t multiply or divide two numbers unless there’s a g-dd-mn good reason that you need to multiply or divide them. And, that’s what I thought about here.

So, you need to make the case for what you did. I can see the ratio of Shuts to Melts. I can see the ratio of IP*LI to G. I do NOT see the reason to multiply the two sets of results other than more-is-better. I also don’t see the need to divide by xFIP other than less-is-better. In the end, what is the unit?

I don’t want to discourage you in trying to come up with something. But I do want to discourage you to just slapping things together like that.
