I tend not to look at the different circuits and their peculiarities, in the same way as I judge a car by its abilities over a season (which, of course, change with the upgrades), although these are always subject to who is driving.
Which is why I don't believe that Nando was especially lucky - he is the single most consistent driver this season - his lowest position is ninth, 2 wins, a second, a third, 2 fifths and a seventh. Of course, this may change throughout the rest of the season, but at the moment I would like to think this is more down to skill than luck.
