Last evening my grand-daughter and I were shooting until "dark". I had cut the bottom out of a 10 oz. foam cup and had used a straightened paper clip to attach it to my mostly black block target.
When it got too dark to see my arrow shaft in my peripheral vision... my accuracy greatly improved. I wonder if it was because the arrow shaft was no longer visible, and so, was not a "distraction"? I always thought I used the arrow, at least subconsciously, as an aiming reference (pointing with it).
Anyone else ever experience this?
