I have a TB in a race that is doing really poorly. Today I compared it to the other bugs, and neither seem to have moved very far. This led me to the conclusion that I have probably travelled further myself during the same time, and wanted to check this.
Since I couldn't find a way to check this I suggest this as a new statistics: the distance I (or any other cacher) has travelled from cache to cache during a given time.
(I wouldn't put this high on the priority list, but it is a nice to have if it is easy to implement.)
