Will, Bob, Perhaps the reason the F is lower than expected is because the breast-height girth is sill incorporating some of the basal flare of the trunk http://www.nativetreesociety.org/fieldtrips/north_carolina/coon_branch_white_pines.htm and http://groups.google.com/group/entstrees/browse_thread/thread/cea43ab22aa60c0b?hl=en A girth measurement above the flare would be lower, thus the F value would be higher.

The Coon Branch Pine is 148.8 x 15' 10" and 1035 ft3 volume. That girth is equal to approximately 2.52 feet radius. therefore F = 1035 / (148.8)(pi)(2.52)(2.52) = 1035 / 2968.62 = 0.349 This is relatively consistent with Bobs observation: " For forest-grown pines in the age-class of 150 years or more, the F factor will commonly be between 0.38 and 0.44. Stocky old-growth outlier pines may achieve a factor between 0.45 and 0.47." Ed Frank "Two roads diverged in a yellow wood, And sorry I could not travel both. " Robert Frost (1874-1963).
