thanks for your very thoughtful and elaborate write-up !
I just got my new M3 SMG and fully share your observations, exspecially the surprise that the shift-time is not at all as fast as I expected, epecially at relaxed engine speeds...
However, afte a few weeks of getting used to, I must say I much better understand the system now and it really DOES have all the qualities, which I was hoping for..
Re. your opinion on the advantages of "lifting-off" slightly especially when accelerating harder, I have not really tested it enough to have a conclusion.. Just a question on the timing..WHEN do you actually lift-off..Is it a fraction of a moment AFTER selecting the next higher gear on the selector..? Some people from my BMW dealer tell me, that staying on the throttle results in a more "robust" upshift (eventhough probbly not as smooth..).
Thanks for your insights !
