Table 7: Qualitative information: determining the value for .

Simulation 1
 Largest % deviation from the expected level of performance of the  4 simulations

Simulation 2

Simulation 3
 Smallest % deviation from the expected performance level of the  4 simulations

Simulation 4

Note that in the simulations, the correction factor is set to which implies that the user may have underestimated by 5%. Note that the value for can be zero. The values are calculated as the perceived inefficiency divided by the observed values.
