Discussion: Criticisms of the "correction factor" verification method [1]

Seven criticisms of the correction factor verification method are discussed. The correction factor C _k approach is equivalent to the GCI, but with a variable factor of safety (FS), which increases with distance of solutions from the asymptotic range. It is found that when solutions are between the intersection points, GCI approach is more conservative than C _k approach. Variable FS that increases with distance from the asymptotic range is a common-sense advantage of correction factor approach compared to GCI.
