For example, a perfectly asynchronous shower can be changed to a galloping asynchronous shower by making the higher throw slightly lower, and the lower throw slightly higher. Shifting the timing further will end up in the synchronous shower. Carrying on even further still takes us to the Half Shower.

Timing Variations can result in an otherwise mechanical and uninteresting Juggling Pattern having more charm than might otherwise expected, and such changes are often subtle, elusive and unexpectedly effective.
