The cardioid/hypo-cardioid spacing can be adjusted to suit the acoustics, source width, and required stereo recording angle, but the omnis should always be 10cm further out to each side.... according to Tony, anyway. :-)
Balance the directional and omni pairs to taste...
That's interesting, I take it the two outer most mic's are Omni's? and the two in the centre are cardioids?
That diagram is very confusing, it gives the impression that one colour is cardioid, and the other colour is omni, but that doesn't make sense,
