Votes are tallied at national level and in six constituencies, each of which has nine constituency seats in parliament. Nine additional "equalization seats" are distributed to constituencies and allocated to political parties so that the parliamentary representation of each party and each constituency will reflect as closely as possible the total votes received. This is done by solving a pair of simultaneous equations! It does have the effect you describe, forcing out some "constituency winners" and replacing them with "equalisation candidates". This seems to be accepted because the constitution demands that every vote shall have equal value. But of course, you don't need to do it this way, nor does the proportionality have to be just "party PR". With STV-PR in multi-member districts the voters have the power to choose the winning candidates on whatever PR basis matters to those voters. I do appreciate that STV is totally unacceptable to quite a number of the more vociferous members of this list, but STV-PR does address effectively many of the issues that arise in electing properly representative assemblies.
