There is only one proper frame alignment. The bb shell is the starting point, the seat tube, head tube and dropouts (both sets) are all aligned with respect to the bb shell. When that is done correctly, there's no question the wheels are aligned and the bike tracks straight. It's not rocket science, the concept was clear to me when I was first introduced to it at 15 years old. That's how Mark Mueller does it at Waterford, I assume every competent builder understands it.
