Same here, no problems playing and scoring my own APA 8-ball match. I also have the problem with teammates that go out of their way to avoid scoring for 9-ball. :-(
I can play APA 8-ball and score my match, and it doesn't distract me or bother me.
It is difficult to score your own 9-ball match and keep your head in the game properly. I can do it, but I'd rather not. Fortunately, it is a rare circumstance for me.
