Good dance lesson. Very well presented. Just one quick comment --
You make no mention of the lead-follow principle that states that an object (or follower, as the case may be), once set in motion, will tend to stay in motion until acted upon by another force (presumably another action by the leader).
In other words, it's not necessary to have a "eight connection" over every step. Once you start the follower moving in a direction, you can let go and she should still keep going.
Do you not subscribe to this theory?
