Zelenskyy’s posting volume on X during the September 11–18 window reflects sustained high activity driven by intensified Russian drone and missile strikes across multiple Ukrainian regions, including nearly 500 Shahed drones launched on September 12 alone, alongside civilian casualties and infrastructure damage. His ongoing official visit to Canada for defense cooperation talks, drone production agreements, and air-defense support discussions has generated multiple updates in English and Ukrainian. A Deutsche Welle interview released September 12, in which he reiterated willingness to meet Putin at the December G20 summit in Miami while criticizing sanctions easing, further contributed to daily output. Trader consensus centers on the 60–99 range because these patterns align with his established pace of frontline reporting, diplomatic outreach, and responses to escalations during periods of active negotiations and strikes. No major scheduled summits fall inside the resolution window to push volumes substantially higher or lower.
