Your "facts" happen to be wrong in this instance, but it is not a CX issue so this whole discussion is too far OT. I do know the pitch is irregular, so it is probable that some seats are at 64 inch pitch and others at 70 inch, maybe with several other values in between. The A345 wound up being a very oddball config for a lot of reasons (it also has a corpse locker, for example, for storing bodies of pax that die in flight; unlike BA who use F seats for that purpose).
