My understanding of Andy's schedule in his push to close in on the #1 ranking is as followed
Tokyo : 1/10/12 Singles & Doubles 500 points
Shanghai : 7/10/12 Singles 1000 points
Basel : 22/10/12 Singles 500 points
Paris : 29/10/12 Singles 1000 points
WTF : 5/11/12 Singles 1500 points
==================================
Total points 4500 points
As you can see, if Andy progresses deep in each tournament, apart from one week break from 15-21st October, Andy will be participating in 5 tournaments in 6 weeks, with the last 3 tournaments in consecutive weeks !
Can his body handle the stress ? I think Andy should drop Basel to give his body a fair chance to recover so he can compete well at the WTF against the very best otherwise he will very likely run out of juice comes the WTF.
