What he means is - don't juggle four in that way! Juggle four by doing two in each hand, in a vertical plane parallel to your shoulders, the throws happening asynchronously. It's *way* easier than juggling 5, and similarly *way* easier than juggling 4 in a 5 pattern with one missing. These SiteSwaps with 3 help a lot:
... 333 42 333
... 333 4440 333
... 333 441 333
Your code should be more efficient!
