OK I've tried a bit harder now.
You are completely correct.
It will force a change up from 1st to 2nd in manual mode when you hit approx 6300 rpm (inside the red zone).
I still reckon your remarks regarding holding it in gear on a fun twisty road were misplaced though - after all you're not actually going to want to rev it ~6300 and hold it there - and it would be quite a coincidence if the maximumm speed you wanted to do in a particular gear would correspond to say ~6400?
It was fun finding all this out though ;)
