...what's the "consensus" thought on the "round-off" number (0.80-0.84, etc.) that's applied to compensate the "rectangular" area value (width x height - gnd clearance)?

...I've seen anything from 0.80 through 0.90 being used, but 0.84 seems most common.

...also, anybody know the CdA for the original Studebaker Avanti that turned 171 mph at Bonneville?
