Re: "Curves for double and multiple sampling are matched as closely as practiabel."
When single, double, and sequential sampling plans have matched OC-curves, they have been designed to have OC curves as close as possible to the same OC curve. The purpose for matching is to be able to use one OC curve to represent the different decision rules.
So it is acceptable practice to use the OC curve calculated from the single plan for the double plan, etc. You can also match variables sampling plans to attributes plans. See:
