Does the g-save reduce gas bills?

Well, I'm afraid that even after three and a half month's testing the jury is still out. I've got gas meter readings from the period 28 November to 13 March over the past three years. They are as follows (in cubic feet):
So, even with the g-save, I've used more gas this year than in either of the past two winters. However, not much more than last year, and this most recent winter was much colder. I know we put the heating on more than normal, and left it on longer than normal, so it's not as simple as the headline figures indicate.
Looking at the imeasure graph of the period, gas use in December was significantly up on the same period last year. The question I can't answer though is, would it have been an even bigger spike if I hadn't had the g-save? Quite possibly.
During the period of mid February to mid March 2011, our gas use was significantly less than in the same period last year. Again I don't know if that was due to better weather or the g-save or a combination of both.
I'm afraid that this is all a bit inconclusive, but my gut instinct is that we used the heating a lot more than normal this year, and that without the g-save our gas bill would have been a lot worse than it was. But, as I say, that's a gut instinct, based on how much we pressed the override button, and not on solid statistics.
