At pinnacle (not sure if this goes for everyone) you can circle to land in VMC conditions only with no additional training required. At pinnacle VMC is 1000ft ceiling and 3 miles visibility or higher if the circiling mins are higher for that runway.
so say for example the reported ceiling is 900 ft. the chart says you can circle at 700 ft. we would not be allowed to circle because we would need 1000ft to be legal for our op specs, even though the chart says we can go lower.
