Hah.
There have been so many chapters wasted detailing the process and results of the Strength, Endurance, Intent and Techniques.
Do you think it was for fun? Those chapters involved so many numbers ffs!
It was because the testing system wanted to extract the details of each candidate thoroughly, from their body power to their combat abilities and comprehension, all for this prowess test!
One could say that the prowess test was the actual test under the Test of Body exam!
In order to make sure they could fully dig out your prowess, they gathered details about all your abilities and then tabulated them before creating foes here for you to vanquish. So for the others who had foolishly done their best, a foe of equal strength basically meant a foe with strength equivalent to the maximum output you released in all previous rounds.
