Yellow and red share a line 20 cm from the lower cushion; white is higher. The object balls are near that side of the table, but they are not frozen to the cushion and not within a 1 cm gap.
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 | 142 | 110 |
| Yellow | 95 | 20 |
| Red | 185 | 20 |
What to compare
Choose an object ball and compare two contact thicknesses from the same position at fixed pace. Observe both the cue-ball departure and the object ball’s movement toward the nearby cushion. A thin contact is an option to study, not the only legal or useful answer.
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
Missing an object ball is not a cue-tip miscue: those are different events. If a thicker contact changes the route, inspect the ball and cushion sequence before assuming that all forward energy has disappeared.
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.
