Reference positionArrival: 0Spin: 0Spin 0: the cue ball reaches the top corner exactly and opens 2 diamonds from ball 2 at the 4th cushion. Arrival 0 + Ball 2 0 + Cue ball 0 = 0.

Spin = Arrival + Ball 2 correction + Cue ball correction
Ball 2 higher: spin −2Arrival: 0Ball 2: along the cushion (±1 per half diamond): -2Spin: -2Ball 2 one diamond (two half diamonds) up along the cushion: −2. Arrival 0 − 2 = −2. The opening at the 4th cushion is still 2 diamonds.
Ball 2 lower: spin +2Arrival: 0Ball 2: along the cushion (±1 per half diamond): 2Spin: 2Ball 2 one diamond (two half diamonds) down along the cushion: +2. Arrival 0 + 2 = +2.
Reference position, spin 0Arrival: 0Spin: 0Arrival 0 (corner) → spin 0. Opening at the 4th cushion: 2 diamonds.
Reference position, spin 1Arrival: 1Spin: 1Arrival 1 (half a diamond from the corner) → spin 1. Opening at the 4th cushion: 3 diamonds.
Reference position, spin 2Arrival: 2Spin: 2Arrival 2 (one diamond from the corner) → spin 2. Opening at the 4th cushion: 3.6 diamonds.
Reference position, spin 3Arrival: 3Spin: 3Arrival 3 (one and a half diamonds from the corner) → spin 3. Opening at the 4th cushion: 4.3 diamonds.
Reference position, spin 4Arrival: 4Spin: 4Arrival 4 (two diamonds from the corner) → spin 4 (maximum). Opening at the 4th cushion: 5 diamonds.
Ball 2 one diamond off the cushion: spin −1Arrival: 0Ball 2: distance off the cushion (−1 per diamond): -1Spin: -1Arrival 0 + 1 diamond off the cushion (−1) = −1. The openings at the 4th cushion do not change.
Cue ball to the left along the short cushion: spin −1Arrival: 0Cue ball correction: -1Spin: -1The ball 2–cue ball extension crosses the bottom short cushion one diamond left of the corner: −1. Arrival 0 − 1 = −1.
Cue ball up along the long cushion: spin +2Arrival: 0Cue ball correction: 2Spin: 2The extension crosses the right long cushion two diamonds above the corner: +2. Arrival 0 + 2 = +2.
Example: spin 2.5Arrival: 1.5Cue ball correction: 1Ball 2: along the cushion (±1 per half diamond): 1Ball 2: distance off the cushion (−1 per diamond): -1Spin: 2.5Arrival = 1.5 · Ball 2 = +1 (half a diamond down along the cushion) − 1 (one diamond off the cushion) · Cue ball = +1. Total spin: 1.5 + 1 − 1 + 1 = 2.5.
Example: spin 0 (give a little spin)Arrival: 3Cue ball correction: -1Ball 2: along the cushion (±1 per half diamond): -2Spin: 0Arrival = 3 · Ball 2 = −2 · Cue ball = −1. Total spin: 3 − 2 − 1 = 0. Even though the spin is 0, give a little spin to make up for the spin the cue ball loses when it strikes ball 2.
Doblete: spin −1Arrival: -1Spin: -1The cue ball goes to the right long cushion as its 2nd cushion. Arrival half a diamond from the corner → −1. Spin −1.
Example: spin 0, but lower the hitArrival: 0.5Cue ball correction: 2Ball 2: along the cushion (±1 per half diamond): -1Ball 2: distance off the cushion (−1 per diamond): -1.5Spin: 0Arrival = 0.5 · Ball 2 = −1 (half a diamond up along the cushion) − 1.5 (one and a half diamonds off the cushion) · Cue ball = +2. Total spin: 0.5 − 1 − 1.5 + 2 = 0. With a high hit the path opens too much (alternative path); lower the hit, down to a middle hit if necessary (main path).
