Then, at this level of precision, you can use the derivative of those peaks/valleys and come to an actual numeric value that would accurately convey the "smoothness", if you will, of said system.
fraps has frame times. just like the excel sheet i showed.

@ keithlm on that pic you posted with the two graphs you can see that one stays about the same and one varies up and down. the one that varies has about the same average, has a higher max and has the same min. but thats not what you want to see. that is the idea of what kind of chart i would like to see. a chart showing the times it took the frames to be produced over time. with the time taking for each frame to be a data point. like you said in a perfect situation it should be a straight line.
