Actually, I find them fairly straightforward to interpret. I particularly
like the comparison approach, providing multiplier values to demonstrate
slowerthan/fasterthan and the associated degree of either!

What's missing, I suppose, is an explanation of what each operation is truly
doing. By the varying N values, I'm guessing that there are some number of
high-level scenarios in play, but each step of the scenario is measured.
That is, if the scenario is "merge a branch into the trunk", you will have
measured each add of each file and dir, each commit to built up some
history, the copy to make the branch, and the merge itself, plus maybe some
status/proplist to verify state. Is that (roughly) what's going on? In
that case, explaining each "add" (for example) would be unwieldy. But maybe
explaining the high-level scenarios would be useless?
