reduces the number of winning parties by picking the strongest ones from each faction. This reduces political fragmentation
proportional and majoritarian at the same time - from parties you marked on your ballot, your votes go only to the collectively stronges ones
fully proportional - you can pick any ballot and easily tell which party received how many votes from that ballot
the simplest score-based PR system

each candidate collects votes for his/her party. Party votes are summed up and seats allocated proportionally
