I have seen no signs of samples hitting the most expensive instruction in ETW trace. Across other cases I have looked at the samples tend to cluster after expensive instructions, not on them. I guess it's possible that all of the cases I looked at were distorted by macro fusion but I don't think so.

Interesting, so I guess ETW is using "normal" interrupts which have skid, and the CPU just having enough retire bandwidth to retire everything in one cycle.
