Perhaps a slight modification: the farther down the list, the more an upvote should count (because of the top-comment bias), with it being unnecessary all together for the current winner... If someone is up-voting a comment farther down, they not only went to the effort to scroll, and they should be rewarded for actively curating, but it means they had to endure other comments higher up that were not as worthy, which is an increasing burden the further down the comment was found (for example, a geometric weighting of upvotes). It might mean more flapping of the position, but it also ensures equal (fair) exposure of equally-good comments. The submission ranking, I assume, takes more into account than just upvotes (age, number and quality of sub-comments, etc). The top-comment problem feels like the same problem, so might be an opportunity for code consolidation.
