Drying shrinkage
Estimated change of a dimension while drying.
Formula
Change % of green size = S · (MC_start − MC_end) / 30
(MC_start limited to 30 %, the assumed fibre saturation point)
Assumptions and limits
Linear shrinkage between the fibre saturation point (about 30 %) and the target. S is the total shrinkage coefficient for the species and direction (radial, tangential) from a source you trust. Real boards also distort.
