Short shifts are better than long shifts in general. But this point of view comes from the fact that short DC shifts are better than long MT shift mostly because their is significant time with no power and hence with deceleration when shifting with a MT. DC systems change this game quite a bit. When shifts can maintain or even increase acceleration during the shift (using engine and flywheel momentum) then the length of the shift becomes almost irrelevant. I have not yet tested S5 nor S6 but because S4 shows no deceleration and actually shows acceleration (above and beyond the steady state in gear acceleration) during the shift, it is hence faster in overall acceleration than D3. S5 and S6 offer even more feeling of surge and hence they are almost for sure going to be even better accelerating than S4 or any D modes. Hope this helps.
Sorry and I re-read everything again. I stepped back and view it from a totally new perspective leaving behind the old adage that you lose speed while shifting, which obviously you don't with a dual-clutch system. Everything makes perfect sense now.
