*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.
