I'm afraid I didn't follow what you're saying. In the MMP system, normally, the way it's done in Germany and elsewhere, half the seats are constituency seats. The rest of the seats are not strictly proportional seats, but they are in a way because the votes on the right-hand side of the ballot, which go to determine what percentage of the total seats each party gets, determine the final share in terms of the percentage of votes that each party gets. That's how it works.
EVC doesn't work that way. EVC works by directly electing the proportional seats. That's the difference.
