White and red are low on opposite sides, while yellow is higher and left of centre. “Diagonal” names the spread; it is not an instruction to hit a cushion intersection at exactly 45 degrees.
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 | 40 |
| Yellow | 110 | 110 |
| Red | 240 | 40 |
What to compare
Compare the path to yellow first with the path to red first. Mark separate cushion contact points rather than aiming at an idealised mathematical corner. Restore the position before changing contact thickness or side spin.
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
A ball has radius and cushions have a real profile. Contact near a corner must be inspected as an actual sequence, not assumed to be a perfect symmetric double reflection. Check the first departure and subsequent cushion contacts individually.
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.
