I'm expressing a different viewpoint, not attacking you.

The transmission varies its shifting style based on how it is being 
driven. Chances are if you had the car for an extended period of time 
it would shift more aggressively if you thrashed it.  Still, you 
won't get jerky shifts because power delivery is never interrupted. 
Which is the -entire point- behind the double-clutch arrangement of 
the DSG.  It is the holy grail of transmission technology for 
performance driving.  No interruption in power delivery means (among 
other things) no weight shift problems, so mid-turn shifting sounds 
plausible.

Skip Barber cars are syncro-less transmissions, or at least at the 
school at Lime Rock. Hardly push-button shifting- they require 
double-clutching and heel-toe techniques.

>Maybe the DSG needs only a couple of iterations to perfect its behavior?

  How are butter-smooth .008 second upshifts and .6 second downshifts 
with no interruption in power delivery not perfect?  Granted the 
downshifts could be made faster, but at a certain point you're 
limited by how fast the engine can get to the target RPM without 
tearing itself apart.
