Furthermore, the table layout were fairly open with maybe 2, 3 clusters at the most. Position is always tight on a 7 ft. so the balls not clustered were still in very close proximity, but racks were definitely runnable with good patterns and speed control. Pros would most likely get out 80-90% of the time with the layouts I was getting.
These are the best results I've ever gotten in approx 3 years of playing at this place, much thanks to the people who responded with such helpful insight!
Be careful thinking the same break approach (cue ball spin, speed, placement, and aim line) will give similar results on an unfamiliar table.
In my experience every table can give widely different results even when using the same set of balls and the Magic Rack.
The key is to be able to quickly determine what adjustments to your break approach need to be made to get the results you are expecting.
For an example of the impact of table behavior watch Dr Dave's video on the 9 ball break controversy, whereby his "trained table" led to a false positive result in his testing. When he tried the experiment from the other side of the rack the results were quite different. He corrected the problem, but it shows how a seemingly small issue in table conditions can have a large effect.
