Ok footie. I think we're on the same page. My understanding is that the higher modes do shift faster and in the fastest modes it fastest modes when the clutch engages the engines speed is faster than the gear selected and so therefore the energy that would have been wasted waiting for the engine to spin down is now converted into the jerk/surge. The slower settings then take a bit longer so that you don't feel the jerk/surge.

If that is the case, and we could be wrong on that, but if it is then it does make sense to offer the lower modes if you want a gentler ride. Same philosophy as EDC I guess.
