Not sure if I have missed the point here but I see that in the OLBA example
The OP said this:
Sabenaboy, well yes OLBA is not a good example. You are right. Disregard the limitations on the circling sectors, it’s my fault on the selection of the airport.
Assume there are no limits on the circling maneuver. Main question is if you are legal to fly overhead for a circling assuming you haven’t reached the MAP yet
If you read the from the beginning it is clear that he is talking about the general case even though he picked OLBA and came up with a scenario with a vis where you could not even proceed beyond the FAF let alone the MAP.
