Yeah they all count. He's also less vulnerable on clay, short of meeting another top 8 player. I don't think anyone else could really challenge him. So I expect he will reinforce his position somewhat there. He will need to find some serious form for the upcoming North American Masters and US Open though if he's to ever return to the top 4.
Very slim chance of missing out on the World Tour Finals, short of retiring before-hand (unlikely, I think).
For the O2 do you mean that any player can play as many tournies as possible to build up his points tally?
Shame that you do not think that Fed will drop more in next few months on the main ranking. I understand your view. I still am being positive on my prediction for his end of year ranking. I had him down to lose early at Wimbledon which caused his plummet downwards so sometimes things go to my wishes! On the brighter side Delpo will overtake him if he does not get injured and is motivated enough. Berdych will probably slowly catch him but he is prone to unpredictability. None of the others seem to be consistent enough to make a big move but I only need those two and one other to do well and it is 8 for him. Ferrer I expect to drop his points level but not enough to drop below Fed and I assume that Nadal can play a little to keep topping up his total at a time when he has nothing to defend. Good position. He can find a few clay matches? These extra events could give Fed 750 points for the Race but can he have both Halle & Gstaad included for the rankings? I should know this. He needs all the points that he can get to have any hope of being near to achieving top 4 status again. Three failures in the next five events would be major damage to his aspirations. Now at 5 he is more at risk of a good player knocking him out relatively early as his draw position is too low to have that protection of the top 4 ranking. From here, with his evident fading speed on court, it is a slippery slope downhill? A bad O2 result could be the final blow. Unless of course he wins at three or four of his next events, and an even worse thought at the US Open..........................
Time to move on with the new breed of players. It is happening on the ladies side so there is hope of same for the men?
