Usually naiive ('Rough') timing tests with rpm do not disable 
un-needed checksum cross checks, key verifications, and such, 
which are senseless in a closed or protected build environment

Publishing the testing harnesses would permit evaluation of 
such -- absent a second person checking the methodology, it is 
probably premature to start kinkering.  Publishing final 
numbers without a reproduceable methodology is just not good 
science
