I have a 'double anchor'....its there...I just get 'on target' fast because I'm aiming before I draw, and I bring everything to me and my line of sight.
I drag my thumb base knuckle to the corner of my mouth and keep drawing....my middle finger contacts the corner of my mouth(I shoot split finger)...I keep drawing ....which pulls the corner of my mouth rearward till my thumb base knuckle slides behind my jaw under my ear....only then is the arrow released.
