Free Software to assist running a Derby

Free software to assist in running a Pinewood Derby or other race. Automatically uses Partial Perfect N charts, takes care of lane assignments and scoring. Nice. Please read all items, or at least the one dated today, so that you're aware of two bugs. I don't know if you're out there anywhere, dknowles67, but thanks for the software, and if there's any chance we could get you clean up those two things, that would be sweet.
