I think someone needs to check on the definition of Mayday, as compared to Pan. I believe that the main difference is that Mayday means "requiring immediate assistance". Is 411A suggesting that a crew losing an engine never requires immediate assistance? Perhaps he needs more CRM training - use the resources you have, and they include ATC.
The fact that one pilot got his priorities wrong in a sim practice certainly provides no evidence that Pan or Mayday calls are overused. I have heard some exemplary emergncy calls.
