Like 868X said Citaro want to have major share of Citaros. Abt
the OCs haiz. Maybe WL want to have major share of MANs
No logic, Because right from the start the citaros were 'evenly
distributed' 139U-143G, 144-148T, After that 149R-151H 154A 156U
169H 177J 181X 182T 183R 186H 187E 188C to KJ, 152E-153C,158P
160G-166R 175P 176L 180Z to AM, 157S 159L 167M 168K 170C-174S and
178G to WLDEP and the sequence went haywire from then on.
