This page now opens the app’s Plus reference layout: white left, red right and yellow high between them. The historical URL contains “50”, but this layout does not establish a Korean 5-and-half calibration at diamond 50.
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 | 36 | 71 |
| Yellow | 178 | 120 |
| Red | 248 | 71 |
What to compare
Choose a clearly defined starting line and cushion reference. Record the scale you use before calculating. Compare a measured return at fixed spin and pace; do not mix Corner-5 and Plus numbering or infer calibration from a preset name.
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 reference line is repeatable but the arrival changes, separate table response from changes in the inputs. One successful model shot cannot calibrate a physical table. Use the linked system lessons for their explicitly stated numbering conventions.
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.
