Relative to the OP or not, these are a few of my observations from playing in the APA leagues for 15 years:
1.) There are varying degrees of all the skill levels. As one example, there are strong SL5's, normal SL5's, and weak SL5's. This applies to all skill levels. The stronger of the skill level is going to beat the weaker of that same skill level more times than not.
2.) A poorly kept scoresheet can sometimes be the difference in one's skill level. I've turned in scoresheets that I had marked 25-30 defensive shots for the five matches played whereas the opposing team scoresheet had very few marked. What's the APA headquarters supposed to do with that???
3.) No one (LO, Division rep, etc.) ever comes to observe the play of a player that has been complained about. Or any player for that matter. We had a kid on our 9-ball team that was an honest SL2. Couldn't make three balls in a row with ball-in-hand (missing a lot of BIH shots). Scratches about 5-6 times a match. He had an average winning %. If anyone saw him play, they would agree his skill level was correct. He is the worst male pool player I have ever witnessed in league play. One session he played about 3 or 4 games above his normal game, got moved up to a SL3. That poor kid lost his next 14 matches before he got moved back down to a SL2 the next session. Then he wins a couple of matches and gets moved back up to a SL3 (where he is to this day). He now only wins an occasional match. This is clearly a case of moving a bad player up because of a rare few games of playing better, when his overall performances clearly shows him to be at a SL2 level.
My point is with this kids story, the scoresheets don't always tell an accurate story. Let me give you another example:
My wife was a SL3 in 8-ball from the time she first started playing about 10 years ago. Her lifetime winning % was right at (almost exactly) 50%. One night she was playing a SL5 (who also was a division rep) in 8-ball and the match went hill-hill. Her opponent had two object balls left and in prime shape to put the match away, but he scratched shooting the first ball. My wife got BIH and with a timeout was shown how to run her last two balls out to get on the 8 (which was out in front of a corner pocket about 6" away). She preceded to make her balls as instructed and won the match. The next week she was moved up to a SL4. Wouldn't you think that a player who started life as a SL3, played all her games in 10 years as a SL3 and had a 50/50 winning percentage would just be accepted as a SL3??? (Equalizer system to perfection)
Now....she would have lost that match had it not been for her opponent scratching. The scoresheet ONLY reflects the fact that she won, not the way that it was handed to her. If she would have lost that match, do you think she would have still been raised to a SL4? The scoresheets have no way to determine whether or not luck was a factor in a win or loss.
I could go on, but I digress. Over the years I've learned to just show up and play my best. Sometimes you just have to try to outrun the spot whether it's fair or not. It's still fun, win or lose.
