While we wait for the final submissions to come in, another fun chart for you. Instead of ranking, it's number of points below the leader, so it shows how the spread of scores has changed. I haven't edited this one to separate concurrent lines, so some people might have part of their line hidden again.
However, it's a nice demonstration of what I said before - round 3 had two leaders, five trailers and the rest clumped together in the middle - now at round 4, the scores have all spread out.
Also shows some trends like Buddy staying in 3rd place but gaining a lot of ground on the two leaders.
