If one or more of the actors are the same, the implementation is still compliant with this Profile and it is expected that the measurement performance will be improved. To give a sense of the possible improvement, the following table presents expected precision for alternate scenarios, however except for the leftmost, these precision values are not Claims of this Profile.

Precision is expressed here as the total deviation index. 2. A measured change that exceeds the relevant precision value in the table indicates 95% confidence in the presence of a true change. 3. A 95% confidence interval for the magnitude of the true change is given by: ± the relevant precision value. 3.
