Shouldn't WR be 6:20.59?

Thank you for pointing this out. While it is common for runners to submit a faulty time, it is ultimately up to the moderator who verifies the run to make sure everything is accurate. Unfortunately, this moderator is well known for inattention to detail and mismanagement of leaderboards. I'm sorry that you were affected by such an issue.

Thank you for the suggestion. This leaderboard does not need centiseconds yet because the top times are not all too competitive.
