Sight window on most bows today are cutout past center about half to three quarter inches. Doing the math on a multiple pin sight guard and you probably aren't having much issue with your anchor point. Just the way it is with anything over a 1.5" diameter pin guard. I prefer small pin guards, but I also never center the guard unless as comes natural with a single pin sight.
I am the growing minority. I like to let the subconscious mind do what comes naturally. That means centering the pin. I have enough problems without consciously trying to make my mind do two things it doesn't want to during a shot. But I'm the red headed step child these days. Not really a right or wrong way of doing it, but I personally will always take centering the pin over the alternative.
