same value experimentally assessed. On this diagram, the ideal line is represented by a linear function with unitary angular coefficient. The points located at left of the ideal line (dashed grey line of following figures) correspond to theoretical values lower than the experimental results. Therefore, if the sample points shift at left of the ideal line, the theoretical model provides conservative results.
