*Note: The stored on-center spacing is used as the maximum allowable spacing.
Therefore, it is assigned to the side with the largest entered pitch. In this example, the
“irregular” side pitch is larger than the “regular” side pitch; thus, the irregular side is
calculated using the maximum on-center value (16 inches). If the regular pitch side
had the larger pitch, it would require the larger (16 inches) on-center.
