Very curious, this election so far

It's nearly 3am and I am still up watching the election.

I have seen a 16% swing to the Torys, an 11% swing to the Torys, and a 5% swing to the Torys.

Why aren't the Torys gaining more seats?

Take Edgbaston, the Torys need a 2% swing to gain the seat, but it is on a recount.

This is a very strange election so far.
