I think this depends on workload still because IO heavy apps hyperthread well and can push up to 100%. I think most of the apps I've worked on end up being IO bound because "waiting on SQL results" or the more generic "waiting on downstream results" is 90% of their runtime. They might spend more time reading those responses off the wire than they do actually processing anything.

There are definitely things that isn't true of though, and your metrics read about right to me.
