I'd heard the term, but it was totally Skilgannon that knew enough to suggest it. Once I looked into it, though, it was pretty simple.
But I also wanted to mention, I was planning to pass some object with all the confidence interval info you might need about the current battle in the new listener. I figured that was among the things you'd want in the application output, since it's among the things I print in the console version. But of course you're free to use whatever you like. :-)
