My source is working for LBR for 3yrs and although a pattern was seen for series 1-10, series 11 boxes have not been consistent. I have opened over 100 boxes in the past couple months of series 11, all sealed and fresh and both myself (as staff and as a collector), coworkers and customers have noticed an inconsistency of a distribution. In the past year TLG is attempting to minimize resellers, allowing current product to be sold for retail value or less worldwide; both policies and distributions have changed in the past year to reflect that intention. Of course there's characters that are produced more than others but I wouldnt be too upset about the distribution as some others are ;p and I wouldnt rely on it too much on it either :)
