级联变戏法的一个关键变量是变戏法者在一个手循环中抓住被变戏法的物体的时间比例，也就是说，从抓到扔的时间与从抓到抓的时间的关系。空间-时间限制和频率锁定的原则建议3/4作为主要比率，2/3和5/8作为最容易的选择。在5个实验中，对象的数量，质量和类型（球或围巾）一起操纵的频率，对象被玩弄。用5或7个球，比率为3/4，与频率无关。对于3个球，比率随频率降低，3/4、2/3和5/8倾向于独立于由物体质量变化引起的力变化而占主导地位。对于3条围巾，比率与频率成反比，通常超过3/4。杂耍的动态理论的影响进行了讨论的问题，在协调和操作的任务限制作为一个实验策略的相对时间。
A key variable in cascade juggling is the proportion of time that a juggler holds onto a juggled object during a hand cycle, that is, the time from catch to throw in relation to the time from catch to catch. Space-time constraints and principles of frequency locking suggest 3/4 as the primary ratio and 2/3 and 5/8 as the most accessible options. In 5 experiments, object number, mass, and type (ball or scarf) were manipulated together with the frequency at which the objects were juggled. With 5 or 7 balls, the ratio was 3/4, independent of frequency. With 3 balls, the ratio decreased with frequency, with 3/4, 2/3, and 5/8 tending to predominate independently of the force variations induced by variation in object mass. With 3 scarves, ratios varied inversely with frequency and often exceeded 3/4. Implications for a dynamical theory of juggling were discussed with the issue of relative timing in coordination and the manipulation of task constraints as an experimental strategy.
