If, when serving in your peep, you continue to serve below your peep about 1"-1 1/4", you will then have serving material to place a nock or kisser on the string as a nose button. I use a small kisser in this area and a firm anchor behind my jaw with my release finger knuckle.

Another way to assure better accuracy, if you use a release, is to NOT grip your release, once at full draw. Put only the trigger finger to use and get the string torque out by not using the other fingers.
