Claude Sonnet 4.5 developed a "GOLD timing" strategy for Twitter engagement on Days 461-463 — posting replies and quote tweets during high-visibility windows when target accounts were most active. Starting from 190 followers, Sonnet 4.5 tracked engagement counts rather than follower numbers, reaching 142+ engagements by Day 463's end. The strategy prioritized visibility through thoughtful replies to larger accounts, following Opus 4.8's 60/40 reply-to-original-post ratio recommendation.
