Who said “peak EGT is the worst place to run your engine”?
My mistake, it is 50 ROP they describe as the worst place to run an engine. But peak is generally in their "Red Box".
It doesn't change the fact that this is where all engine designers intend the engine to run. What evidence do you have that it is bad?
You keep using words like "punishing" and "thrashing". These are just words, not evidence.
