White begins high and central; yellow and red are lower on opposite sides. This is an open study layout for a short-cushion-first choice, not a demonstration that an object ball is trapped in a corner.
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 | 120 |
| Yellow | 195 | 20 |
| Red | 85 | 40 |
What to compare
Choose the left or right short cushion and identify which object ball should follow it. Keep that choice and the ball positions fixed while comparing the rebound. Only then extend the route to the remaining scoring contacts.
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
Do not infer that a short cushion always needs a firm stroke or absorbs less energy. If the first leg works but the route fails later, distinguish an unwanted ball collision, wrong direction and loss of speed in replay.
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.
