He'll get appr 700-1000 points from optional events. It's 4400- 4700 points in total without Shanghai, Montreal, Cincy, Miami, Madrid, Paris. So, to stay No1 at the end of the year Federer has to get appr 6000+ points.
Well, the worst case scenario has arrived. The only difference is that he won 2 Masters and made 1 final, but he also won Barcelona.
