Since the required share of votes depends on the number of contesters per seat I arbitrarily choose it to be 5 contester/seat.
Multi-member districts (for green and blue systems) are of a magnitude of 5 and 'Uneven" means they have a different number of voters in a ratio 1:2:3... 19:20 or 1:2:3:4 for multi-member districts.
Also, since the Two-round system and Alternative vote allow 2nd and even 2nd last preferred candidate to win the graph shows an average preference, rather than sheer share of vote.
