Several surveys have revealed that these two indices are generally misunderstood. The product of this particular over-scoring of duration and under-scoring of instances is generally close to the call hours (traffic, or Erlangs) measured using automatic call monitoring equipment, so the effect in terms of traffic estimation tends to cancel out in this case, whether it starts at zero or some other value, and.

In a different context, surveys of individuals may find that obtaining an ethnically representative sample is very difficult, perhaps for social or language reasons, resulting in under-representation or exclusion of certain groups — groups such as the disabled or very young or very old are often inadvertently excluded from samples for this reason.
