Notes
Recalculation
The profile curve is not recalculated automatically when distributions change, though the expected value is. It is done this way because the simulations could take a while to run.
Limited goals
Profiling does not address the general optimization problem, that of optimizing quality against cost, given functions that represent all aspects of the problem. This more general problem would benefit from a surrogate model and space filling design to explore this space and optimize to it.
Jagged Defect Profiles
The defect profiles tend to get uneven when they are low. This is due to exaggerating the differences for low values of the cubic scale. If the overall defect curve (black line) is smooth, and the defect rates are somewhat consistent, then you are probably taking enough runs. If the Black line is jagged and not very low, then increase the number of runs. 20,000 runs is often enough to stabilize the curves.
