It would be like breathing the throttle, I think. You can even spin a car on a straight if you aren't smooth.

Do you think if you can upshift in a turn, even on track out, then you aren't going fast enough? Or am I not thinking about everything here?
That is the exactly the benefit of DCT in this situation, at least in S5 with MDM. With the two clutches, the transmission can do such a smooth shift that you DO NOT FEEL THE SHIFT AT ALL. It does not upset the chassis even if you are at the limit of adhesion of the tires.

Now I only need to prove to myself that I can also do this in S6 .
