@JCN, or anyone who cares to comment.
My range used to host USPSA and I had access to swingers. In an attempt to create a more irregular movement pattern I would attach a short rope with a dumbbell weight to the bottom of the pendulum.
This worked okay...but still resulted in a very narrow window of movement.
Today I watched a video on scientific efforts at describing and controlling Chaos. And I saw something that looked promising.
A Double Pendulum.
If someone with too much time on their hands and access to a well equipped private range(hint) were to make a steel target as the second pendulum...
Where the colored circles would be a steel target of TBD size.
Versus this.
I think that the DP(no porn intended) would allow practice on an erratically moving target that provided immediate feedback on visual tracking control, trigger control and shooting at assessment speed.
Thoughts?
