> I am looking for a way to assess stress in Performer. I know that the stats graphics display a wavy red line that indicates when the system is stressed by straying outside of a certain boundary, but I am looking for a better way to quantify this measurement. Is there a variable in pfStats that holds the values used to draw the red line? Any assistance would be appreciated.

The stress management in Performer is inherent instable from a control theory
point of view. You have to implement your own stress management
with the functions

float pfGetChanLoad(const pfChannel *chan);
void pfChanStress(pfChannel *chan, float stress);

Call these inbetween pfSync() and pfFrame()
