I kind of had this crazy concept I did with my feet during setup on the approach. When I needed to adjust, I would move boards and also would angle my feet correctly too.
Kind of like this.
A. I am standing on board 30 (I am right handed, so I used my left foot, which means basically my big left toe is on board 30).
B. I would line my left foot so it would be square to the foul line. (Foot is straight)
C. Then I would adjust the heel of my left foot. In this case maybe move it 1/8 to 1/2 of a board left.
D. Next I would bring my right foot in line with my left foot.
E. Adjust everything else up from that (Waist, Shoulders, Arm Ball, Head,). Make sure everything is pointing in the same direction.
Using this setup over time, I kind of figured out what targets I would go over at setup.
So if I wanted to go over 3rd arrow I would stand on board 32 and angle my foot correctly. If needed to go deeper off 3rd arrow, I would move to board 36 and angle my foot a little more so I would still go over 3rd arrow, but my angle would be a little more steep.
Does it make sense?
I liked throwing straight at spares, and this really worked for me.
