A Pool Skills Workbook: Cue Ball Speed and Spin Progressions

Cue-ball control improves faster when each station changes one variable and every finish window fits on the real table segment. This workbook uses a 4 × 8 diamond-coordinate model, exact ball centers and a named pocket so the rolling, stun, follow and draw routes can be rebuilt and checked.

Coordinate pool-table diagram showing cue ball and object ball centers, a real corner pocket and four legal follow finish windows
Original Ariakon coordinate map with one scale on both axes. Ball radius is0.09 unit and target-circle radius0.045 unit for the declared example. All follow centers remain before the real corner.

Build one legal reference line

Ball centers, not ball edges, define every coordinate. Use removable marks and confirm that the local side-pocket opening leaves room for the farthest center window; shorten all forward windows together if it does not.

Shoot without sidespin. If the object ball misses the named pocket, record zero for pocket and position even when the cue ball happens to stop in a window.

Forward targets(2.312, 5.890), (2.625, 6.281), (2.937, 6.671), (3.249, 7.062)Centers are 0.5, 1.0, 1.5 and 2.0 units beyond the object-ball center

Score four sixteen-attempt stations

Station A has no collision and isolates delivered rolling speed. Station C uses the pocketing shot, holds the chosen medium-speed routine and changes the forward-rotation result. They do not share a score or infer one skill from the other.

For Stations B and D, measure one ball diameter in local diamond units. The cue-ball impact center is one ball diameter behind the object-ball center along −u. Mark that point; do not substitute the object-ball center, which is occupied before contact.

Use a half-ball-radius target around each called center. When neighboring windows would overlap on the local table, reduce the radius equally; never move a target after seeing the result.

Sixty-four attempts; 128 possible points

A — Rolling speedCue ball only from (0.500, 1.000) through a one-ball gate at y = 2.000 to centers (0.500, 3.000), (0.500, 4.000), (0.500, 5.000), (0.500, 6.000)Four each; 1 gate + 1 finish inside a half-ball-radius window; /32
B — Stun/stopCue-ball starts 1.0, 1.5, 2.0 and 2.5 units behind the object ball on −u; call a stop inside one-ball radius of the measured impact centerFour each; 1 pocket + 1 stop gate; /32
C — FollowCenters (2.312, 5.890), (2.625, 6.281), (2.937, 6.671), (3.249, 7.062)Four each; 1 pocket + 1 called forward window; /32
D — DrawFrom the measured impact center, call 0.25, 0.50, 0.75 or 1.00 unit back along −uFour each; 1 pocket + 1 called return window; /32

Graduate by station, not by total alone

Worked example: the player scores A 27/32, B 28/32, C 23/32 and D 14/32. Follow is one point below its threshold and draw is the lowest score, but progression starts with the first failing station: twelve attempts at the nearest follow window. Draw remains queued until follow clears.

Record cloth, ball condition, date and miss direction. The result describes this layout on this table; it is not an official playing rating.
