Well, yes, I understand that there will always be variation
when benchmarking. What I don't expect and don't understand is
why there is apparently no variation while it is running. The
only variance is between different instances. I would expect
a run to look more like:
3467 frames in 5 seconds = 693.4 FPS
3684 frames in 5.001 seconds = 736.653 FPS
3653 frames in 5 seconds = 730.6 FPS
3648 frames in 5 seconds = 729.6 FPS
3683 frames in 5 seconds = 736.6 FPS
3758 frames in 5 seconds = 751.6 FPS
3717 frames in 5 seconds = 743.4 FPS
where it varies across the entire range of possibilities
(which would account for various load factors). But instead
what I observe is that it is extremely consistent in any
one given run, only varying between different runs.
