Hopefully this'll make some form of sense - based on Kami's suggestion of a 'recent entries only' leaderboard, tried to create a format that doesn't just total the points (or else that only favours those regular entrants) or one based only on percentage of votes (because this means one shot participants who did well will have a higher percentage). TLDR: And for the more specific method.. though still work in progress if I can improve it. Each PJ person's rounds score (halved where necessary for the non voting) is divided by the number of possible voters in the same round. This gives more value to that song that got 100 points in a 20 person round than a 35 entry one. These are then added and divided by contests entered by them in the ten most recent rounds. Finally to slightly nullify the 'one entrant only' effect, applied a modifer to the scores - all ten entered and full score counts, only one and it's 75% of the figure.
