The descent profile on the 330 is quite different to the 320 which I both fly. This is due mainly to the huge wing and is exacerbated as we now use engine anti-ice for the descent which increases engine idle rpm. The 320, as with most jets, needs 3 X height but the 330 requires roughly 4 X height. Which means descent at approx 160nms. Thankfully it has got speedbrakes that work as ATC and the descent profile often don't coincide!
Oh, and we all would rather be no. 1 !
