Wouldn't a pilot project conducted strictly during a by-election falsely represent what actually happens during a general election? I don't have any scientific proof, but I've always heard said that during by-elections, voters are less motivated because they're only voting for a representative in their riding and not for a government. So the voter is less motivated when not choosing a government. You know full well that sometimes voters vote for the local candidate, sometimes for the local party and sometimes for the next government.
