I've spent the weekend re-tooling my PITCHf/x data handling. The big step has been to bite the bullet and standardize the data back to y0=55. What was really fun was my Dad being in town and working out the math with him. Also, we spent time discussing algorithms and uses for the data. He agrees with the use of cluster analysis, and he certainly knows a thing or two about signal detection and pattern analysis.
There are about three people who are interested in getting a hold of part, or all, of my process. Some of contributed encouragement, others motivation. Last night, Eric Seidman (from Statistically Speaking) and I worked late into the night (for a work day) on getting his database set-up and loaded. The loading is coming into some issues, but we've made progress.
For me, the last hurdle is the PFX calculations. There are two approaches outlined by Alan Nathan, and I'm having issues with both when converting the work from my Excel scratch-pad to MySQL. Once that is together, and Eric and I are successful on his system, too, I'll be posting my code for anyone to use.

Working on my System

That is stellar that you are going to publish your code. I have a database in My/SQL but no way to really do much with the pitch data. I've already spent too much time on the project as is, as i'm sure you have, and I wish the pitch f/xers would be more open with their knowledge of how to do their analysis. There plenty of intelligent people who don't know about Stats or Physics who could come to understand it quickly if explained. I know there's been some posts but nothing definitive and no code for sure. Thanks in advance.
