If in fact the number of failed polygraphs has increased to 50% from 20% then one would expect the polygrapher workload to have increased nearly 70%. Since a failed polygraph would normally also include an elongated post test interrogation, the workload increase would even be higher. And then if hiring itself increases.....

Does this imply there are a lot of new, inexperienced polygraphers or just the same number of very tired people.
