Grand Company reward bonus requirements?

[Duuude007]

Some info from Connect Magazine:
- When everyone from same company you get bonus as well as when you have 3 different countries grand company members

I wish to clarify this--

Scenario Party 1:
Member 1: GC is Uld'ah
Member 2: GC is Uld'ah
Member 3: GC is Uld'ah
Member 4: GC is Uld'ah

Result: Party is entirely the same grand company, and therefore receives bonus (A)

Scenario Party 2:
Member 1: GC is Uld'ah
Member 2: GC is Gridania
Member 3: GC is Limsa Lominsa
Member 4: GC is Uld'ah

Result: Party represents at least 1 member of every grand company, and therefore recieves bonus (B)

Scenario Party 3:
Member 1: GC is Uld'ah
Member 2: GC is Uld'ah
Member 3: GC is Gridania
Member 4: GC is Gridania

Result: Party represents at least 1 member of 2 grand companies, but not all 3, and therefore recieves bonus (C)


Questions:

Does Bonus A = Bonus B?
Do both Bonus A and B yield unique, special results?
Does Bonus C exist, or is this combination the exception to the rule?

More people seem interested in joining Gridania than Uldah. Not sure who you're talking to if you're hearing everyone clamor for Uldah. . .

When my group did the level 25 fight we had two from LL and two from Ul'dah. All of us received Seal "x2." So I assume it's indicative to how many of the same nation are in your party, up to a maximum of party size.
