No. I change a little bit for each station. I check my swing when setting up at each station to make sure I can make the necessary movement to kill the bird. I adjust my feet to match my swing movement.
Yes I do 2,3,and 4 are the same. 1 and 5 I square off with the house. on 1 my left foot is back-right ahead, just the opposite on 5. I am right handed and after shoulder surgery on my left, I have to open my hips up to catch the hard angles on 1 and 5.
After surgery it is not as easy to swing left or right . Maybe not hard angles but the ones that are not legal but close. Hard angles for me.
Where should I put my feet when shooting from chair? If I shoot with my upper body behind line, then my toes are about 18'' across line. I'm sure this would give me some strange looks and maybe a disqualification? What I've been doing is having feet behind line regardless of upper body.
Foot position should always have your leading foot roughly in the middle of the field for that station. As I move right to next station, I put that leading foot a few degrees to the right each time i move.
