Its good enough for me! I wonder if any dials are aligned so precisely. And the error that this mis-alignment would cause is only 12 seconds in sundial time at 45 degrees latitude. In fact, even if you had a perfect East/West line marked out, I wonder if it is humanly possible to get the dial installed with the gnomon perpendicular to that line with such accuracy.
