There's nothing I missed. I've seen quite a few different patterns. Wherever you place the 2, you'll have a shot a good percentage of the time at running out if you soft-break. If you have it right behind the 1, you would just break on the same side as the 2 ball, have the shot at the 1 in the side or top pocket, and possibly have a chance at the 2-9 combo (I think your opponent would cry though if you did this). If the 2 is the wing ball, you shoot on that side and it goes in the corner with regularity; then you make a judgment based on where the 3 is in the rack. If the 2 in front of the rear ball, you break on that side, and you have a shot at it in the lower corner pocket. And if the 2 is the back ball you'll bank it up the table and have a shot at it after the 1. You could then adjust the speed and hit depending on where the other balls are on the rack. Barring any unlucky clusters, your worst shot will be going up the table, then back down, then back up again. Elite players do this, even with 8 balls on the table, and many good players do this as well.
You won't do it every time, but I'm sure anyone who practices this will do it with enough regularity for some relatively easy runs. And if it doesn't go as planned all the elite players are great shotmakers and safe players.
