Potus used the term "The threshold identification of Ballots " which turns out to be a statistical term:

Threshold is a value. You associate the Threshold to a Statistic (PolledData). When data is collected for that Statistic, it is compared with the associated Threshold value. If the collected data value does not suit the Threshold value then it indicates that this kind of data might lead to poor performance of the device or network.
