Whether the better official consumption figures translate to the real world any better than current figures is another thing.
The problem I find with DSG is that it is so enjoyable/easy to plant your foot and let the car do all the work. That style of driving does not translate into good fuel economy in the real world 
So I can see why many drivers are disappointed with their real world fuel economy.
Does the DSG encourage an uneconomical driving style?
Well, my GTI is the first non manual car I have driven as a daily and I was surprised at how long it took me to get used to it. I ran the car in exclusively in "D", with a gentle throttle, letting the gearbox do what it wanted. Once the car was ready for more beans, I had all sorts of frustration with bogging down, hunting up and down gears and silly sky high revs, coupled with less speed than I intended. For a while, I used the paddles to control things more precisely, but I have found myself using them less and less, recently, as I discovered that, by using the throttle in a more analogue fashion, I could make the car do more or less what I wanted it to in "D". Now I only ever use the paddles when things get really serious! With gentle throttle openings, the box takes a higher gear, but, by squeezing it open, rather than mashing it, the box can be persuaded to hold gears, or kick down. My consumption is averaging just over 35mpg, with mixed driving, which seems to be reasonable.
Having said all that, it does annoy me that, at low speed, I can switch from "D" to the paddles and the nanny dash display immediately tells me I should be in a higher gear! What's that all about!
On a slightly different topic, has anyone found a use for dsg "S" setting? Seems utterly pointless, unless you're on a drag strip.
