Figure 5D. Offset-limited fold plot for Wide-Azimuth Design D. The offset limited fold for design D (10 to15) is only slightly higher than Narrow-Azimuth Design A despite having nominal fold that is more than twice as high. Most of the extra fold consists of longer offsets in the cross-line direction.
