Faulkner does not do this with his array, as he stated that he doesn't like the sound of coincident pairs. Ultimately the combination of omni and directional mics in a single array is not the perfect solution - just a good compromise in many situations that don't permit extensive sound checking and unfettered mic placement. I'm a fan.
One of those compromises seems to be that, if ORTF is used as the central pair, the spatial positioning of instruments across the left to right panorama is different between the central pair and the wider (67cm) omnis.

Thus, if the 2 pairs are mixed together at close to equal gain, there will be a positional 'blurring' of instruments which is unpleasant to the ear....a bit like looking through binoculars with one eyepiece out of focus.

Hence there's been a recommendation to let one pair of mics predominate over the other pair by about 7dB or more, which tends to minimise this divergent image overlay. If the central pair of directional mics are widened from ORTF out to somewhere between 41-47 cms, this image position discrepancy is similarly minimised
