Here's the quote from AF Manual 11-217 Instrument Flight Procedures, for what it is worth:
Circling procedures and techniques are not compatible with precision approach criteria, and under normal circumstances, should not be attempted. Since the MAP associated with the precision approach is determined by the pilot in terms of a DH and not a specific point along the final approach course, it becomes difficult to ascertain when to discontinue the approach if visual conditions are not encountered. Therefore, pilots should not plan to circle froma precision approach.
