Hypotheses: That a Bell Curve Calculus can be built in which the results of arithmetic operations on Gaussians can be approximated sufficiently well by other Gaussians that the resulting calculus can be used to propagate numeric quality of service properties around workflows to provide reliable quality estimate.

Evaluation: Given the mean and standard deviation of the input Gaussians, those of the input Gaussians were experimentally approximated for the range of arithmetic operations needed in various quality of service calculations. The resulting calculus was successfully evaluated on some typical workflows.
