I think you may have misunderstood part of my feedback, and that would explain why the issue continues to be present in your work, with a lot of cases where the far end is visibly narrower than the end closer to the viewer. In your response, you said this:

I feel like I’m doing my best to train my brain to respond instinctively, but a part of conscious reasoning always comes back

In my previous feedback, I spent much of it addressing your concern about understanding the why behind the far end being wider than the closer end, and explaining why the conscious understanding of that is not really that important because outside of this course you're going to be relying on the auto-pilot we develop by following the exercises here. But it seems that this may have caused you to fixate on the idea of relying on your instincts in general, which is not at all what you should be doing when going through these exercises, as further stressed here at the end of my previous reply:

And so instead, we focus on shifting the attention to the exercises, to applying their instructions as intentionally, consciously, and thoroughly as possible.

Based on your own explanation, and the results of your work, you are doing the opposite of this. For the work you do in this course, you should absolutely not be attempting to rely on your instincts. You need to be fully conscious and aware of the choices you're making at every step, so that you can push yourself to make the correct choices based on the instructions. This process of being hyper-intentional (the opposite of what you described as what you were attempting) is what pushes those behaviours down into your subconscious, naturally. You do not train your instincts by attempting to rely on them.

You'll note that in other rounds of feedback, I echoed the same point, for example here in response to your first round of revisions, where you were falling short in drawing through your ellipses:

I can see that you are trying to draw through them, but you appear to be relying on your auto-pilot to do so, rather than actively being aware of the choices you're making.

So to be completely clear, the process you should be following here is one of applying the instructions, step by step, intentionally and consciously. Do not rely on your instincts at all. In fact, this aspect of how we approach studying, by avoiding using our instincts, is one of the major reasons why the 50% rule (as introduced in Lesson 0) is so important - it gives us an opportunity to balance out this learned mistrust of those instincts by ensuring that at least half our time is spent actively relying on them. You can read more about this here.

Please complete the additional 15 cylinders around arbitrary minor axes again, being sure to actively choose to make the farther ellipse wider in its degree than the end closer to the viewer.
