Yes, it's always a risk, a greater or smaller depending on the show. They released, for instance, 4 tickets to Miss Saigon yesterday for a performance in january and I was the first to get one. Today, they sent me informations on my seat and i was designated R2. When I looked in telecharge I've seen R2, R4, R6 and R8 taken. So I'm assuming they got the 4 together and designated them in the order of redemption. By this logic, if there's only one left for your show, you'd get the last seat in that series and possibly there would be a seat available nearby. Of course this is pure speculation and everything could be just random, therefore the risk. I don't know if this helped at all, but it's all I know.
