Why I didn't get DCT, realizing things like this. Sequential shifts are very fast, but 6th->2nd or 6th->3rd takes time, much easier in 6MT. This happens all the time in real-world driving, cruise to hard acceleration. Anecdotes of Schumacher not needing this miss the point entirely. I certainly don't think "pentuple clicking" the paddle is fun or efficient.
Also DCT has slightly higher internal loss - the near instantaneous shift only saves an official 200ms off 0-60, I doubt that number is entirely the difference between a DCT shift and a human shift, likely it's much faster than a human, and 200ms is what's left of the difference with additional loss. *shrug*
