Then the flex algos could be defined using these metrics. Correct? yes, they would need to define a new FAD constraint and/or metric only. I agree that if the goal is a new metric, then that's sufficient. [Plug for generic metrics.] It sounded a bit like Linda was wanting a fundamental change to the SPF algorithm. If, so, I believe that would require a new Calc-Type. Linda, could you please clarify? [Linda] I don't think so. We want a constrained SPF algorithm that take into additional metrics. Just like TE being added into the SPF. Linda Dunbar Tony
