The states Lr and Ll correspond to the arms being crossed, left over right, and if we are to have arrows between them then it would imply that you can juggle with your arms crossed. Well, of course you can. What about inside versus outside exchanges? When most people juggle with crossed arms they do inside exchanges, resulting in a pattern that looks like a reverse cascade. That may require some thought - it's not immediately obvious.
To answer this question, let's look closely at the possibility of doing an inside exchange from Ur to Rl.
Firstly, this means that you start with the arms uncrossed and do an inside exchange with the right hand. This will happen more-or-less on the right hand side of the body, so the right hand throws from around the centre of Juggle Space, moves further to the right, and catches. If this is done in the most fluid and natural way, this results in the arms being even more uncrossed (if that makes any sense) than when they started. In particular, the most fluid and natural movements certainly do not result in the arms being crossed. This possible transition is therefore not included in the diagram.
The same is true of all the other missing arrows. They are all excluded from the diagram because the movements they represent do not feel natural. This does not mean that they are impossible or uninteresting. It just means that they are, in some sense, for the moment, less desirable.
The next few lessons will cover using the diagram to analyse existing patterns, as well as how to overcome the various shortcomings.
