Average Shrinkage Values Of Wood At Various Moisture Content
It calculates at 3 preset values and one for the moisture content you desire to dry your wood to.
The fiber saturation point (FSP) is preset @ 30. This based on that in most publications this is used as an average value but 28% for North American species sounds like a better option. The FSP for some of the tropical species appear to be much lower.
