The fundamental problem is that we can't link the Protection System to the Data Collection system completely. We extrapolated from a sample of several of our nodes on the network and found a high percentage of overlap between the Protection and Data Collection systems -- in the 90%+ range. We ran these tests since the Tuesday following our phone call through this morning to extend the time frame to smooth out any inter-day or intra-day noise. This was a huge effort which required several of our development staff to run manual queries on each node at different times of the day, affecting each computer's Protection performance.

Hi Ben,


Have you been able to run any tests to estimate how much overlap there is between what the countermeasure machines see? When can we expect this data?
