The Average linear shrinkage result is the equally-weighted average of the parallel shrinkage and the perpendicular shrinkage results.
Use this result to obtain a single-figure result indicating the shrinkage within a part. Warping effects, where the difference in parallel and perpendicular shrinkage is high, will not be visible using this result.
Look for regions in which there is high differential shrinkage. These regions are more likely to deform.
