Reading this in hindsight

This page is a permanent record of what the archive said at the time — it is not updated as the market resolves. That is the point: a precedent-based reading is only honest if it stays fixed after publication. A high bullish share was never a forecast that the market would rise; it recorded that most measured charts resembled history that had risen. Method and limits are documented in Methodology & limits.
