... TPA is about impossible to obtain. There are not 10,000 Pat's around to score every game.
At one time, Pat trained scorekeepers at each event to record all the stats. I think he did that for years until about 1987. He found it easier to video record matches and do the stats himself. Some people wanted the VHS tapes, and the rest is a long history.
I think the Accu-Stats scoresheet instructions have been published, and the printed Accu-Stats issues are in the Goldmine. The second issue has an example of what the scoresheet of a match looks like.
