The news from Robin in the update does sound rather bad to me. The fact that it takes a while to get in good shape if you have stopped training for a longer time is of course to be expected. Then you increase the physical intensity little by little, and gradually approach your full level over a longer period. But judging from the update, unfortunately this is not the way it seem to work for Robin, rather he must rest too long after each effort to make any real physical improvements. What one can hope for is that he still does improve, just at a slower rate than we were hoping for.
I hope he gives Indian Wells/Miami a shot. Can't stand to see more 0 pointers. Probably know in a week or two because f he doesn't bother to go to US and practice in early March it safe to say he likely skips the US swing and aims for the clay.
Haven't even watched his schedule but I guess he didn't sign for Monte Carlo so maybe a comeback in Barcelona or a 250 like Estoril. Advantage with comebacking in a 250 is that he got a shot at being seeded despite being around #30 then
