I'll ignore the third point and just ask if anyone on the committee has come across a group called International IDEA.
The International Institute for Democracy and Electoral Assistance is the only global intergovernmental organization with the mission to support sustainable democracy worldwide as its stated mandate. It has amazing resources online, 200 pages of which I read. One of the things it looks at, besides increased capacity, legitimacy, and credibility of democracy, is more inclusive participation and accountable representation.
My only other point is that they have a bunch of charts. They have helped fledgling democracies select their form of government. They have never advocated first past the post, and very rarely advocate the alternative vote, for any other fledgling democracies.
