Introduction

After developing the statistics for combined detection rates we felt the need to summarize that data into smaller charts. These charts are showing the combined performance of the different vendors in pairs. Instead of using a matrix table these are being represented in a single listing.

Charts

These charts are generated once a day from the existing Combined Results charts. We are only showing the first 20 of each table otherwise each chart would be hundreds of lines long.
