White and red share a high horizontal line, with yellow lower and near the middle. Use this spread to compare a long-cushion-first approach to an object ball; the diagram does not assert that a direct line is blocked.
Actual starting layout
Ball centres on the 2.84 × 1.42 m reference table. The link loads this layout with white as the cue ball; it does not play a scoring shot. Coordinates start at the lower-left corner.
| Ball coordinates · cm | x | y |
|---|---|---|
| White | 40 | 120 |
| Yellow | 142 | 20 |
| Red | 250 | 120 |
What to compare
Select one first object ball and one long-cushion contact. Begin with a geometric reflection as an approximation, then compare side spin at fixed pace. Inspect the object-ball contact before trying to complete the remaining cushions.
Record a baseline, restore the same layout and change one control. Record the first contact, cushion order, any unintended ball collision and final arrival. Keep the speed fixed when comparing side spin; keep the spin fixed when comparing speed.
How to interpret the result
If the initial cushion point changes, your first aiming comparison is not controlled. If that point repeats but the object-ball contact changes, compare spin and speed. Short and long cushions do not justify a universal one-tip correction.
A three-cushion point requires both object balls and at least three cushion contacts before the second object ball. A preset name is not a certified scoring route. Compare model results with your own table; no universal hit rate or player endorsement is claimed.
