It may revolve around how well the track "rubbers in" and gives greater life to the tyres. At the moment there is consensus that it will be beyond one stop strategy - that is three sets, 2 hards and 1 mediums v 2 mediums and 1 hard set. If there is "better than expected" life then two yellow sets may be advantageous in the last stint. Red Bull always look after their tyres and so I think there won't be any advantage to take out of it, sadly.
Was there overnight rain again last night to make the track green again for the race as was the Saturday situation?
