Indeed, I don't see the point in establishing specific limits and then decide to "interpret" the values to see if we follow procedures or not. As said previously, EGT during cannot reach the limiting values, if they do, it means they are pushed too far. It will not harm them, maybe not... but maybe it will... who will say? You are talking about something very critical here: even though it is EGT, it is a representation of a high pressure turbine temperature, a very critical point in a jet engine.
Over the limit calls for recall actions, end of story. "Interpretation" is in this case not our job.
If the engine reaches 726°C during start, it's not something too "interpret" too. It's simply not allowed.
