You should be running it several times to get a meaningful picture. The most important number is the max latency.
After an install of the rt-tests programs I am able to run it from snakeoil system page. My figures are -

Wooh. It's terribly high!!
Let me try some changes.. I think the numbers are because of errors in installing program not kernel..

The BIOS / CMOS setting and hardwares also play a role.

Suggest you run cyclictest with a standard system first. That will give you a baseline. Then, within your BIOS, remove all uneccesary settings, unused features etc and rerun cyclictest.
With this foundation, you can then add the RT Kernel, do tweaks like CPUset etc. and rerun cyclictest.
Otherwise, you will be chasing your tail...
