OllPoll - score-based majoritarian party-list proportional representation method

Hi,

inspired by "The space of all proportional voting systems and the most 
majoritarian among them" paper by Speroni di Fenizio and Gewurz, I 
created a score-based system - https://ollpoll.org/about.html

It is a two-pass score-to-vote majoritarian party-list proportional 
representation system and has the following properties:

- score voting based - can score multiple parties and express different 
levels of support
- eliminates vote splitting (in 2023 parliamentary election in Slovakia 
we had 25 parties to choose from!)
- assigns votes to the strongest party in each faction, eliminates 
weaker clones from factions. This reduces the number of winning parties, 
thus reduces political fragmentation
- majoritarian, concentrates power to the strongest parties, but still 
proportionally representative. You can pick any ballot and tell which 
party received how many votes from it
- if you omit apportionment for seat allocation, you can use it in 
multi-winner elections with huge number of candidates and only a handful 
of winners, like US primaries

As with many things in life, when you invent something, somebody else 
had already invented it before. Is this the case with OllPoll? Do you 
know anything similar, except the paper I mentioned? And most 
importantly, do you find it useful?

Cheers,
Oskar
