PDK out of gear at lights?

[NicD]

There was a recent thread re autos but what about the wet and dry PDK clutches?
I like to move to neutral when paused:
Makes me feel like I am doing something mechanical
Removes the slight creep forward.

But, am I wearing more than I am saving?

There's no reason to put the PDK into neutral at the lights. Doing so serves no purpose.

I explained two reasons, here is a third. I can detect the engine speed drop slightly after the load is removed from the shift to neutral.

what is your source or expertise for your assertion?

Of course you can move the selector to N when stationary at the lights if you want to - just as you can with any automatic. It's just not necessary. Porsche says leave it in D.

Yes, agreed it is not necessary, but neither is good driving.

And yes P suggest to leave in D in their owners manual but I interpret that advice as aimed at the lowest common denominator of know-nothing drivers for their convenience.

My question is a technical one. Do I cause more wear and tear by moving into N and back (often with a bit of throttle on)?
