Comment(by BillK):

 I would actually expect something like this when running in power saving
 mode - are you doing so? - try using wmiconfig to set maxperf and run the
 tests again.

 One powersaving technique delays transmission in conjunction with the AP
 so interactions can exist with the various timing parameters.
