You're right, level 7 doctor doesnt speed up the recovery process at all ...
My SG was injured on 6 May 2014, and out for 2 weeks; His status was updated to "1 week" on 13 May 2014. Tentatively, I'd expect he would fully recover by 20 May 2014, when will be around all-star game.
Shame that he's going to miss a tough away cup game on 15 May 2014.
