Is there any information on whether engines allowed to spin freely but, kept below say 4000 RPM are more or less prone to IMS failures than engines that are pushed hard?

Speculation is that spun hard once warm is better as it forces more oil, and the owners tend to more frequently change the oil.
Good oil, and no less than half the recommended interval.
