The strongest argument for YES is the hard physical transit data from the first half of the target window. Maritime intelligence firm Windward and the Joint Maritime Information Center tracked 11 transits on March 31, 16 on April 1, and 12 on April 2. These 39 confirmed crossings mathematically guarantee the 7-day total will exceed the 30-transit threshold, even if traffic drops to zero for the remaining four days. This surge is not a statistical anomaly, but the result of a new diplomatic framework. As noted by the calibration forecaster, Iran has implemented a formal, Omani-mediated toll system near Larak Island. This permission-based corridor has allowed non-shadow fleet vessels, including French and Japanese tankers, to safely navigate the strait for the first time in weeks. Finally, the resolution source's methodology provides a massive structural margin of safety. IMF PortWatch relies on automated AIS geofencing, which the skeptical risk manager highlights has a documented history of double-counting ships drifting on the tide. During the March 9-15 period, this glitch resulted in an official count of 41 transits despite only 21 physical crossings. Unless the IMF retroactively overhauls its algorithm, this hallucination bias heavily favors a YES resolution.

The primary risk to a YES resolution is a sudden, retroactive methodological update by the IMF. Because the PortWatch platform is still in beta, administrators could implement a hotfix to filter out the stationary and loitering vessels currently inflating the count. If this correction is applied retroactively to the March 30 to April 5 window, the reported count could plummet, erasing the algorithmic margin of safety. Furthermore, the physical transit count remains highly fragile and dependent on illicit or controversial trade. The conservative statistician warns that the IMF actively filters out vessels with irregular AIS signatures or GPS spoofing. If the ships utilizing the new Iranian coastal corridor are predominantly dark fleet vessels masking their locations, the IMF's official count may completely ignore the physical crossings tracked by private intelligence firms. Finally, geopolitical volatility could still force a NO resolution if early-week data is revised downward. Western allies, including the EU, have explicitly rejected Iran's new pay-to-pass toll system. If diplomatic pressure forces major shipping lines to boycott the corridor, or if a kinetic strike sinks a vessel in the transit lane, traffic would instantly revert to the late-March lows of 3.4 transits per day.
