Discrepancy in the number of "questions with no accepted or upvoted answers"

Question

I asked a version of this question earlier, but there seems to have been some confusion about what was meant, so I will try to be as clear as possible.

I am NOT asking for an explanation of the difference between "questions with no answer" and "questions with no accepted or upvoted answers". I am asking why there are two different numbers reported for the latter category.¹

On this site, with Unanswered selected in the upper tab bar and newest selected in the lower tab bar I currently get

1,382

These are explicitly described as "questions with no upvoted or accepted answers". However, if I select Questions in the upper tab and unanswered in the lower tab bar, I get:

1,433

This is only a difference of 50, but these numbers are live, and so I'm curious as to which 50 questions count as being "unanswered" that do not count as "questions with no upvoted or accepted answers".

Part of the reason I'm curious here is because if we subtract the number of questions with no answer (~1100), this is the difference between 280 and 330, which is not insignificant.

^{1. Just in case that is not utterly and totally clear: Please, please, please do not explain the difference between "unanswered questions" and "answers with no upvoted or accepted answers". I understand. That's not the question.}

Answer 1

The Unanswered tab in main navigation excludes questions with negative score. You can see this by sorting it by votes and navigating to the last page.

The Questions/unanswered does not exclude negatively scored questions, so its count is a bit higher. For example, as of now this page has negatively scored questions.

By the way, the accepted answer here is incorrect.
