Picking on McLaren again...

So both McLaren's have been each been sent back 5 spots on the starting grid due to purportedly holding up BMW's Nick Heidfeld. I watched qualifying and saw the supposed incident. The live shot I saw of Heidfeld slipping between the two McLaren's made me wonder if a fuss could be raised and upon replays of the incident it looked to me as though in fact the McLaren's had not impeded Heidfeld, I mean it wasn't like he had to lift or anything. Later on Heidfeld said it may have cost him a few tenths of a second which is serious enough time in F1 and if the case is true Heidfeld could have finished higher on the grid saying P2's time was 1:36.230 and Heidfeld's P7 time was 1:36.753 meaning not much time was between grid positions 2 thru 7, so in theory the 5 spot penalty both McLaren's have suffered can't be seen as a harsh punishment in respect to the supposed crime, though I sort of feel it is unjust.
