5 ball Tennis Is Fun?

It's funny and more tricky than I first thought as the outsider ball always wants to become a 6x but has to stay nicely in it's 5 place to avoid disturbing the timing of the other 4 balls.

This Gif diagram makes a funny impression of the struggle to keep everything normal and prevent collisions.

I feel good about small progress but won't stop until I can run 10 rounds and so at the same time feel like I have made some gains on 5 ball stability.
