Digital Queue Abandonment Metric Variance in EU-West BYOC

Trying to understand the calculation logic for the Digital Channel Abandonment Rate within the EU-West BYOC Performance dashboard.

The metric reports a 15% variance compared to the raw Architect flow logs for the same timeframe.

Is this discrepancy related to session timeout definitions?

Specifically, how does the dashboard handle abandoned sessions initiated via the Web Messaging widget versus mobile SDK?
