If it's on rank 1 of the front page, then the vast majority of votes come from the front page. But if it's at rank 90 of the front page, and rank 1 of the new or the best page, then in those cases only a minority of upvotes may be coming from the front page.
If HN implemented this, they would know where the vote is coming from. But on Quality News we could just assume there was an X% chance the vote was from the front page, a Y% it was the new page, etc., and adjust our upvoteRate formula based on that.
