That would be the best thing to do for a woman. But the ATP is not the WTA. I don't think it's possible to make a successfull comeback after one year. Playing less on HC would be the solution, but it's not possible with the calender.
Something like this would help a guy like Federer (he doesn't need it, but just saying). Nadal's form depends a lot on him putting the hours in the practice court and by playing lots and lots of matches. So a break might do him a lot of disservice.. he'll struggle to get back to the top again.
