If I calculate this right and taking into account the state of the race before Dubai started:
Federer 6630
Nadal 6005
Djokovic 5085
Between Dubai and the end of RG here are the points that they have to defend
Federer 2005
Nadal 3350(!!)
Djokovic 1900
Which would leave them each with these points as a baseline
Federer 4625
Nadal 2655
Djokovic 3185
There's a total of 4100 points up for grabs between Dubai and RG (or 4000 if someone prefers to play Estoril over Barcelona). How's this for some fantasy scenarios.
If Djokovic wins every tournament between Dubai and the end of RG then there's no way anyone can stop him from taking over as no 1
(I don't think so.)
If Nadal wins every tournament between Dubai and end of RG. He still might not be number 1 if Federer picks up RU finishes at all the Master events and RG.
For Federer not to be number 1 after RG he'd have to do pretty abysmally. I think if he stays around the 6200 mark then Nadal is going to have to improve his season this year compared to last year which isn't impossible but pretty unlikely or Novak is going to have to win the FO as well as 3 or 4 of 5 Masters Series events as well as go deep in the other events he doesn't win to get to number 1.
Bottom line I don't see Federer not being number 1 till we get into the meat of his season last year which was between Wimbledon and the US Open. It's no impossible for one of the others to get there just pretty unlikely. Nadal though has to watch out for Djokovic. The difference between their two seasons last year up till RG was 1450 points. It's not inconceivable to see Djokovic pick up half that and Nadal lose half that.
