Example showing the predicted grade recoveries from the pruned log models as a function of log small-end diameter for four different defect core sizes (135, 165, 195 and 225 mm) and two different maximum branch sizes (20 and 60 mm). The recovery of knot-free grades (#1 Clears and #2 Clears) is affected by log diameter relative to the size of the knotty core, while the recovery of knotty grades (No1 Framing, No2 Framing and Box) is also affected by maximum branch size
