Someone check my math here I may be suffering from slept through math-atitis

The first car on the list
Acura CL 1997-1999 Height = 54.7 Width = 70.1
frontal area = 21.6 ft^2

My math

54.7*70.1*.84/144=22.37 ft^2
Am I daft or is the page wrong????
Looks to me like .81 was the frontal area "correction factor" used.
