Golf tees may be okay, but this is more of figure 8 sighting, which is okay. I did this for some years - arrow hitting at the top of my pin at all distances.
Years back I'd finish my practice routine by shooting quarter size dots from 25 yards. I would shoot 5 of them. Sometimes it took more than 5 shots
I also use to shoot these are far back I could see the dot. Sunlight just right, 60 yards is along ways.
