tare = c(21.2, 21.2, 21.3)
wet = c(115.0, 135.7, 126.2) - tare
dry = c(99.0, 113.3, 108.8) - tare
vol = c(3)*pi*(5.31/2)^2 # = 66.44 cm^3
moist = 100*(wet-dry)/vol

I think the 10/2 density and moisture-by-volume calculations are slightly off. given a volume of 66.4cm^3, I calculate the 10/2 beans density=1.49g/cm3 and MBV=24.08%. Should I update the table?
