I understand how the ranking system works, I just wanted to know the exact points calculation for the scenario being discussed. For instance, can Fed afford to not win Basel (i.e drop a few points there) and still get back #1 from Djoker who will drop all his Basel points. I guess I would get my answer if I looked up how much the point differential between these two would be if Fed loses to Wawa and Djoker wins Shanghai.

Thanks, that answers my question.
