Practice this TML pattern on your table until each one becomes a known and trustworthy shot.
The reverse spin on the cue ball brings up the pattern short of the pocket. A lot of the energy is lost at the 2nd rail as the reverse spin is converted to running English.
The 2nd and 3rd rail fully converts the cue ball to running English. This is
The angle changes from the 1st and 2nd rail cancel out any running English benefit. The ball still comes into the corner at the almost exact line. The 1st and 3rd rail contact are almost exactly on the head foot string.
Other Sized Tables
For 8 foot tables, the same type of pattern requires about 1-1/4 tips out from center to get the paths shown. For 7 foot tables, 1-1/2 tip out from center is necessary to follow the pattern. The distances on small tables are less, so when the cue ball travels around in a trapezoid pattern, the rail contacts are more distorted.
