Future PR probably does involve some math, but I have no clue how that works.

Well, as I'm always the first to say, there are certain types of technical details which I pretty much ignore. So if you say the tool queries datacenters and gets an xml file which it then processes and extracts a number to display as a live pr, I'm happy to stipulate.
I instantly sort everything I study about the SE's into two categories - practical use and no practical use.
Once I've put something into the no practical use pile I tend to flush the details from my memory, and store a synopsis. So, that was my summary.
I still don't see a practical use for it. It's a little amusing that the "real" google pr is so easily available, as a number in an xml file, when google goes to so much trouble to obscure it.
But I don't see a way to convert that into sales, so I'm planning on dumping it back into the no practical use bin.
