Airspace Structure; Procedure
New SOP in effect requires right downwind traffic to San Francisco be vectored between two points depicted on video map only a few miles wide. This requirement never existed before. Vector off arrival route to remain between these points must be timed very precise and can be affected by wind; aircraft performance; workload etc; etc. I was sequence delay vectoring aircraft to SFO; picking up VFR aircraft; issuing approach clearances and coordinating a HAF GPS approach. My vector to the right downwind left the aircraft slightly south of the southern point now required in the SOP. Delete this unrealistic requirement in the SOP. There are too many variable factors and too busy a sector to keep aircraft between these points all the time. Concentrating on this vector to comply with the SOP will deter from other more important sector duties.
NCT Controller voiced concern regarding newly established vectoring points on the downwind to SFO; claiming the precise vectoring required is unrealistic given other position responsibilities.
