counting the political boundaries

I've been looking at a few of the analyses of the polls and thought I'd spend five minutes doing my own. In many scenarios the numbers yield an interesting skew to the outcome.

Because of the adjustments to political boundaries and the non-proportional voting system, there are all kinds of unexpected splits that occur if there isn't an outright winner with half the seats and an outright majority.

Before the election, Labour has 345 seats, which is a proper majority of the 646 available. With the varied swings predicted, this could drop by 75-90 seats, spread between Conservatives (mainly) and Liberal Democrat (some).

Its interesting, because with the lowest percentage of the overall votes (27%), the Labour party could still finish with the most total seats of the three parties (259).

With a more evenly balanced split with the most votes going to a mobilised Conservative party (34%) then the next to the Lib Dems (30%) and the lowest to Labour (28%), we'd still see the most seats go to Labour at 267, then Conservative at 255.

And supposing the Lib Dems managed to get the most overall votes (33%), with Conservative at 32% and Labour at 27%, then we's still see Labour with the highest number of seats at 259, and Lib Dems with around 128.

Some of this doesn't seem quite right to me.
