By "whole show" Koz means the whole selection. You could be zoomed in on part of the selection and not see the peak that prevented Amplify or Normalize having any effect.
I was gunna say that.

We have been known to use Amplify to tell us where the highest peak in a show is. Run Amplify on the whole show and if the top number is 3, then the highest peak in the show needs 3dB boost to bring it up to 0 which is the default target value (bottom number).
It's one of the three "manual tests" that ACX Audiobook people can use to test their performance for ACX technical compliance.
— Measure Peak Sound. [No higher than -3.0dB]
Select the whole clip by clicking just above MUTE.
Effect > Amplify > Read the top number and CANCEL. Do Not Apply the Tool!!
Edit > UNDO if you apply it by accident and the blue waves change size.
