Optimum Choice of Verification Query Times

As previously stated, the prototype system performs the verification based on the states in the state queue.

One method of choosing the verification query time would be to query the entity based on the frequency of the data we are trying to monitor. Assuming the simulated data is correct, query or sample in such a way as to perfectly reconstruct the data, e.g. based on the maximum frequency component of the monitored data. A possible drawback is that the actual data may be changing at a multiple of the predicted rate. The samples may appear to to be accurate when they are invalid.
