Its 870 mm span is 3% narrower than typical for the area — the median across the 136 current wings within 10% of its size is 902 mm.
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a comparison inside the area tolerance may be comparing unlike figures.
