When resolving by sight, the pattern to look for is usually a "sandwich" with the key couple paired in between the 2 corners.
For some setups, most notably that needed for Dixie Grand, it is much easier to see the patterns of the required setup with this method than with any of the others.

However it is not the only Dixie Grand setup. The other pattern has the primary couple facing each other far apart in one column and the corners nose to nose in the center in the other column. Because the arrangement is known in [0P], it is not necessary to know which corner is where because their gender determines which of the two spots they'll occupy.
