book for explanations, details, examples, and more information)
NOTE: Even though the cue is nearly level in this video, there is a slight
amount of swerve,
and the effect of the swerve is larger for slower speeds.
Therefore, the observations
in the video are for "effective squirt"
(the combination of squirt and swerve).
For more information see my series
of articles dealing with squirt and swerve.
