A B C D Cab Naming

[RobinKhoury]

Can anyone explain what the letters A B C D mean in the Cab IR names?
for example:
220 — 4x10 Super Verb 57 A — FAS
221 — 4x10 Super Verb 57 B — FAS
222 — 4x10 Super Verb 57 C — FAS
223 — 4x10 Super Verb 57 D — FAS
Does it denote different mic positioning? If so, does anyone know what positions correspond to each letter?
Thanks.

Does it denote different mic positioning?

Yes. And possibly a mic mix as well.

If so, does anyone know what positions correspond to each letter?

Nope. Fractal had purposely been vague about this so people use ears over eyes.
