- Why it was chosen
- The Melissa case demonstrates performance in joint track and intensity prediction and collaboration with official agencies.
A model scores each item twice, independently, against one written standard, out of 100. An item is admitted only when the two scores add up to twice the threshold. The threshold is set per source tier.
