However, rules are one thing and in practise they might be ignored for the greater good (of your favourite party, of your career and so on). So what is your point of view as to how well the systems work. No donut-shaped constituencys?

I saw somewhere a graph over what number of seats different parties could expect from different election results in the UK. What I remember was that Labour had the biggest advantage and could be expected to have a majority of the seats if they got an equal or better result as the tories and the Liberal party stayed low. The liberals had the worst position and needed to be considerably larger then the two other parties to get a majority of the seats. I guessed at the time that this was because of gerrymandering, but if that is not the case I guess labour has the best distribution of support, with tory second and the liberals third.
