Rolex Fastnet 2025 analysis of what OSCAR’s 424-boat replay, first-hour comparison, detected 16° shift, and Fair GPS limits can support.

The question
Where did the Rolex Fastnet 2025 fleet first separate, and what can the public track record actually support?
What the replay shows
This dated source snapshot does not support naming a definitive geographic first split. OSCAR presents a 424-boat replay whose Story view includes a first-hour comparison, one detected 16° wind shift displayed at 05:30 AM, and leg-by-leg analysis. The annotation does not show a timezone.
What it cannot establish
The header labels the replay Fair GPS, and the race facts report fair data quality (61/100). Tracker pings are minutes apart: this post-race replay cannot establish every onboard decision or why a crew acted, and the detected shift is not a universal sailing rule.
