K's have a face of 25 and P's a face of 1,000. This yields a ratio of 40 by my math 1,000/25. That's correct, but that's just the mathematical theoretical perfect ratio. In the real life, if you get any days PPS you will see they don't reach the 40 ratio except on a couple of times. I'll show you: http://img155.imageshack.us/img155/9529/ratiow.jpg
