i went for a 7 - never give 10 or 1 on principle because as soon as I give a 10 something else will come along and beat it, or if I give a 1 something else will come along and manage to be even more dire - in either case I'm buggered because I didn't leave myself any wiggle room.
This was a good race, pretty much edge of the seat for decent amounts of time, even if some of the entertainment value was screaming at the ineptitude of McLaren's pit-roadies (for the second race) who whould be strung up by the prunes IMO.
