I updated my set of spreadsheets of score sheets for Accu-stat matches that I own to include the 2009 US Open stuff if anyone is interested in looking at them.

My final TPA's are not an exact match with the ones that Accu-Stats publishes. I have found that this is usually due to:

1. Differences in opinion as to what the player was trying to do. In these cases I listen to what the commentators think and go with that.

2. Taking the scoring system too literally. Accu-Stats used to not count the following as errors and now seem to do so.
  • A kick that pocketed a ball would not produce a position error.
  • If an opponent kicked a ball in from a safety that did not allow them to see the ball it would not be considered an error.
  • Playing position for an intentional safety was not considered a position error.
3. The Accu-Stats list is sometimes just plain wrong. I have seen some summaries on their tapes that say a player scratched on the break an incorrect amount of times. (I think I can judge this stat with 100% correctness). One match they even got the final score wrong.

I also have what I call a success percentage which is marked as SP on the sheets for each match. This calculation is based on total number of shots taken instead of total balls pocketed. It counts safeties and kicks not resulting in pocketed balls and only counts one ball per successful break. It also considers a break that does not pocket a ball to be a failure. Personally I think this number is much more accurate as to the outcome of the match.

Anyways, they are located at https://sites.google.com/site/accustatmatches/Home. If you have any problems seeing them just post a reply and I will look into it, but sharing should be setup correctly.
 
will you post or direct me to something that states exactly how pat's scoring system is followed.

There is a legend and format page link off my main page for the spreadsheet notations. If you want to see how they compare to the Accu-stats scoring here is the link to their library which has a link to their TPA summary page: http://www.accu-stats.com/Library.html

The main differences in the way the marking is done on my spreadsheets is that I use a 'Y' instead of an 'n' to indicate easy misses and I annotate kicks in the special shots section rather than by using circles. I also separate out the balls on the break from the shot totals. These changes allow me to automate some of the calculations.
 
Even though I think that Accu-stats may make a mistake or two in their scoring I know that my scoring sheets may have some errors as well. If you see any, please let me know so I can improve their accuracy.

Thanks.

I updated the site to include my scoring of all the 2010 Derby City 9-ball matches and added the Fat Boy Challenge matches to the score sheets for 2009 and 2010.
 
jjr, this is really nice stuff. A lot of work.

It's a blur of numbers to me so I wouldn't know what to look for, but you would:

Have you noticed any oddities or unexpected results or patterns in this stuff? Does the guy with the higher TPA always win? Is there a correlation between successful kicks and the eventual match winner? Or successful safes? Does the guy who missed more balls almost always end up losing the match?

There are many examples where the loser had the higher TPA. A good example of this is the US Open final with SVB and Ronnie Alcano where Ronnie shot almost 30 points higher. This usually happens either when the player with the lower TPA had a better success rate on the break or the higher player had a few racks where they pocketed a majority of the balls and then failed to get out.

There really isn't a correlation between any numeric total and the outcome as a lot of the time the winner will have more errors simply because they were at the table longer.

This is why I came up with the Success Percentage (SP) formula that is in the lower right corner of each score sheet. This percentage takes into account shots that are not included in the TPA calculation such as successful safeties and kicks as well as breaks that fail to pocket a ball. Therefore if a player plays a lot of successful safeties that probably was the major factor in their win this will show up in the SP. Although there are a few exceptions, the player with the higher SP is usually the winner and the exceptions are usually hill-hill matches and not by nearly as much as with the TPA. Just look at the match I mentioned:
TPA: Alcano .919, SVB .892
SP: SVB .901, Alcano .863

Very cool stuff, Jamie. I was a little surprised to see the TPAs for the Klatt/Immonen match. After it happened, people were talking like Klatt shot a 1.000, not a .943, and Immonen shot .980. I'm sure it was impressive as hell to watch, but there was a big difference between Klatt's projected TPA and his actual. After watching this match, do you have any thoughts on it?

The official Accu-stat TPA for Klatt was .972 which means that they only marked one error for him. I assume that this means that they either did not mark him for the position error which I believe cost him what should have been his first runout or they did not mark a safety error because Mika made a difficult shot; maybe they counted it as a kick in which case the player cannot be credited with a safety error. Please keep in mind that these scoresheets are based on the way that I saw it and if you or anyone else reading this wants to challenge any mark I make for any match I am willing to listen and make a change.

As for the large difference between what he got and perfection, he just did not pocket a lot of balls. For him every error is going to .028. Mika's error on the other hand only cost him .010 because he pocketed almost three times as many balls.
 
I posted the 2011 US Open score sheets if anyone is still interested. See link in my signature.

One thing I would like to note is that Darren Appleton has now shot on the accu-stats table 9 times and has shot a .900 every time. This year he beat Johnny Archer who shot a .948 against him and Jason Klatt who put up a six-pack and a .940 only to loose to him as well. The man is a machine!
