Here's the problem with pattern racking, in a nutshell (or in a video, if you will).
Dennis Orcollo runs a six-pack by pattern racking and soft breaking.
The pattern, from our point of view:
Two
Four, Three
Eight, Nine, Five
Seven, Six
One
After two racks he reverses the five and the eight for the next five racks (including the rack that stops the run).
Two
Four, Three
Five, Nine, Eight
Seven, Six
One
Balls pocketed:
Five in the upper right
Five in the upper right
(Switches the five and the eight)
Eight in the upper right, one in the left side
Eight in the upper right, one in the left side
Eight in the upper right, three gets kicked into the upper right by the two
Eight in the upper right
Eight in the upper right, one in the left side
It appears that the runs are easier when the one does NOT go in the side, leaving him a shot into the side or upper left if he over draws the cue ball.
The run ends when the one goes in and the two fails to come off the bottom rail into the middle of the table because it got kissed. That forces him to push out.
Edit to add, if you want to see the after-break positions, go to 4:00, 7:00, 11:15, 14:45, 17:45, 20:30, 24:15.
