And an aisle seat in the front of the plane would be zone 5 or 6. On intra-europe business most of the 'C' seats in business are zone 5, while 'D' seats are zone 6 etc. And if your seat changes at the boarding gate / lounge etc, then your zone would automatically change too.

Is that the really big M that prints on the bp you are refering to. If so, that is just to tell the whole-world from a mile away (including the glaring lounge matron) from a mile away that you are a lowly economy pax

And a similar big C prints on the same yellow business class bp's.
F class bp's are red and have a lovely looking big
F plastered all over them.

Strange though that the letter of the alphabet that I hated most while in school is the letter that I soooo love now as an adult
