Both Divian's Dragon Crystalline Armor and All Mouthy King's Infinite Slash were complex techniques that only individuals that were in the top rankings were able to perform. As such, it was not surprising that no one was able to analyse both techniques to give an accurate conclusion. Even comparing the techniques simply by its strength or evasiveness was hard to do. The calculated risks and thought processes, the underlying skills and techniques contained within them…there were simply too many factors to be accounted for.
Furthermore, the speed at which the two were unleashing their techniques was astounding. Even experts would have a hard time keeping up with the constant barrage of attacks. Calculating the strength of each technique was not something that can simply be done in a couple of hours. The fight along had already went beyond the level of Elite Division. Not even an expert like Laura would dare to claim that she had completely understood the fight in its entirety.
