I believe I claimed to be good at this.  An important part of "good"
is spending the effort required to sanity-check what you document.

Yeah, I think the way I'm going to handle this is to drop back to 
giving 10mSec as "expected" and then list factors that can degrade 
that towards 100mSec.

And that goes on the list of negative factors.
