are you asking whether there's a difference when using the paddles when the gear lever is in D or S? i haven't actually noticed myself, but i would've thought that once you activate the paddles and it switches automatically to manual, it wouldn't matter whether you're in D or S...?
do you also find that in D it shifts up way too quickly and never seems to want to shift down unless you're almost coming to a stop? and as you say, in S mode it only shifts up just before the redline, regardless how hard you're pushing it, but it does downshift more easily.
based on my slightly longer experience with the steptronic system in BMs, they seem to take into consideration how hard you're pushing it when deciding when to shift up/down.
and we can do what we want when we want if we want....
