Description Said Abou-Hallawa 2015-11-30 12:45:34 PST
The test complexity bounds (min-max values) are used to prevent the test FPS from fluctuating. We always make sure the current complexity of the test is within these bounds. These bounds are the min-max values of the test complexity starting from the beginning of the first overshoot till the end of the following undershoot of the FPS.

We need also to make sure that the bounds are large enough to allow some flexibility. This is helpful when the difference between the lower and upper bounds is very small. I think it is enough to make sure the lower bound is at least 90% of the upper bound. The bounds are negative in the case of graphics benchmark since the relationship between the test complexity and FPS is reverse proportional. So we need to apply the adjustment to the "absolute" minimum bound which is (min if min < 0) or (max if max < 0).
