That's the whole secret. Certainly the more the engine is being stretched to the limits the more one has to do to prevent failure.
These informations/findings are not coming from fralind but from user Rika back here in Germany (as Jeff might know).

Thanks for clearing this up...totally makes sense. Its amazing to me what goes on inside of a engine! I worked on jet engines years ago, including build up...reciprocating engines are much busier and more fascinating.
Be safe,
