You think you ride that type of ride the same way you behave in a fast group ride or racing, or intervals or sprint workouts?
I have never ever had a problem in that kind of application either. On a heavily loaded bike I do not go stomping on the pedals or riding up hills in the big ring standing. I do everything as smoothly as possible to avoid getting hurt and to conserve energy.
You do something like shift into a tall gear in the big ring and start a sprint effort at low RPM you get huge spikes of force through the drivetrain that you don't get when you try and ride smoothly.
Different types of riding.
FWIW I never said Shimano rings give trouble regularly. Every Shimano crank I bought new at Retail or came brand new on a bike seems to have the rings torqued perfectly from brand new and never gave any trouble.
