My guess is that is because the timings are very short. In general I
have noticed some irregular behavior, it is a good idea to profile
multiple times.
There are some limitations and reasons for irregular timings written
under the 'notes' section on digitalmars:

Finally, on some machines, the windows high performance api can have
bugs (I have such a machine, motherboard issue).
