After repeatedly banging my head against a wall to try and find any lingering problems with this work (metaphorically speaking, that is), I realized that the setup for Mr. Ericson's log was rather lacking. As such, he seemed like a bit of a misery-guts. Well, he kind of is, but not an interesting misery-guts. However, after agonizing of a way to fix this problem, a solution came to me:
I was focusing too much on one aspect of the story and not enough on the other.
'The Mysterious Teacher in the Suit' is half of the story, but its part wasn't there! I tell you, author blindness is a pestilence of mine. I'd looked over the article and looked over the article so many times, I was just thinking the ideas without actually writing them. A common mistake of mine, but one easily rectified.
Ta-da! Here is the Abridged Test Log Edit, which should address some of the problems with his 'arc', so to speak. Of course, the main problems I wished to tackle were brought to my attention through other perspectives, which (as I have recently learned) is my saving grace. Thank you very much to everyone who shared your opinions of my work with me! Even if something's imperfect, I only feel joy when it's mentioned because I know that I can fix it.
That said, I also appreciate anyone who had no problem with it before, though in a slightly different manner. As a side note, it tickles me to hear that emotion appears to be my strong suit. It's one thing to tell myself that I'm good at what I do, but it's quite another to hear it from someone else.
To sum up, whether you complemented or criticized, thank you very much for your words! Hopefully, the improvement is noticeable and, indeed, an improvement. Peace!
