During one of the matches a players takes a cut on the nine ball to win the game. It's a thin cut that is hit fairly slow. The nine ball reaches the jaws of the pocket and then appears to stop there. After a short period of time it falls in. It would hard to say for sure how long it seemed to be motionless before it fell.
Let's say it was close to what I believe is the five second rule.
While the nine ball appeared to be motionless the cue ball is still rolling down to the far end of the table. On an average table it takes a slow moving ball about four or five seconds to travel the length of the table. The nine ball fell just as the cue ball came to rest.
Now the question is when does the clock on the hanging ball start. Does it start when the object ball appears to stop moving or does it start when the cue ball comes to rest?
Did the cue ball hit a rail as it came to rest?
Personally, I believe all balls have to stop rolling before the object ball rest 5 second rule goes into effect and then my opponent must have a calibrated stop watch that has been tested by an approved calibration firm.
