Conventionally, VTNA results are presented by comparing "bad" with "optimal" overlays (Fig. ). In contrast, Auto-VTNA offers a more detailed visualisation of how changing order values affects overlay (Fig. ). As the degree of reaction profile overlay is calculated for a range of different order values, a plot of overlay score against order value(s) can be produced. Thus, researchers utilising this method can justify the optimal reaction order in a quantifiable manner.
