I recently went on the tour of the site again, for no real reason, and I found that the example question was 'Is an olive tree frost resistant?'. My answer to that question has five votes, townseans answer has six and is accepted. In the tour, though, my answer was shown as accepted and with a much higher vote count. Is this a bug, or are the numbers arbitrary in that example?
If you go to /tour on any Stack Exchange site, you'll see the same thing: a sample question with a score of +14 and two answers with a score of +3, with an animation where the bottom one gets another upvote and the accept mark, and switches places with the other one.
So it's not a bug, it's just the way that the graphics on the tour page are put together.
