that's very clever i have just looked at it for military of the polish lithuanian commonwealth and likert scale and it was very interesting it is still analysing revisions for list of colours would it be possible to modify it so that the user can specify how many revisions back it goes and maybe have a default or recommended value of for that parameter that would make the feature reasonably quick it would also mean that long forgotten edit wars don't get a re airing which could be a good or bad thing depending on your perspective
