I don't think this is about curtailing anybody's participation. I think it's actually more representative, a reflection of representation in the House of Commons. It has always struck me as somewhat odd that parties with fewer seats actually end up with occasionally two or three rounds when sometimes the government's own members, the opposition members, and other parties don't even get their own members through. I think it's fair.
