Many operators run their PT-6's at less than maximum ITT (T5) for a number of different reasons. Some are newer operators, who are looking
to increase tbo times. Others, as mentioned, are attempting to take some of the sting out of a hot section replacement.

What everyone failed to remember here, is the simple fact that there is a reduction gear box connected to this thing, hence the maximum continuous horsepower ratings. If you have ever seen one come apart, it's uncontained, and parts will wander through the fuselage.
