Moving the pinion in or out will not change the contact pattern from heel to toe, it will only move the pattern deeper into the root of the teeth or out toward the top edge of the tooth. Heel to toe is mostly affected by the cut of the gear and the alignment of the pinion bore machining to the carrier bearing bore. What you are looking for is the pattern to be centered between the root of the tooth and the edge of the tooth with a rounded edge on the pattern and not a pointed edge on the pattern.
