Interestingly, LC4 is merely doing a brute-force churn. I'm unable to program any sort of a pattern into it. In theory, if I were able to give it my pattern, it would have them all in a scant couple of hours. But currently it's saying it'll take over a day to do the whole list. I'm going to put it on a system that's about 6 times faster than this one, so an overnight run should be enough.
