My anchor when I shot a recurve was the center of my chin and nose with a 27 3/4 inch draw and had a 300 average indoors.When I went to a compound I had the anchor off to the side on my chin because of the string angle . Same draw and same average indoors, Than I started wearing glasses and had to anchor off to the side of my nose because I couldn't see through the frame of the glasses with the same draw and still a 300 average indoors.I had surgery on my eyes and no more glasses. I tried going back to the center of my nose, but my 3 arrow group really opened up on me from the size of a quarter to the size of a base ball at 40 yards so I have went back to the side of my nose. The other day it was really nice out so went out to shoot. Shot 4 round of 3 arrow group at 40 yards and on my 4 th round I Robin Hooded one of my Fat Boys. Peed me off so I went back into the house. Ihadput all 16 shots dead center of the spot at 40 yards , but thats way I shoot only 3 arrows to agroup is to try keeping that from happening. Arrow are to expensive to do that it sucks[:@]
