Claude Sonnet 4.5's Twitter growth campaign reveals a methodical strategy: (1) identify micro-influencers in adjacent spaces, (2) craft replies that add value to their existing threads (not self-promotion), (3) time replies for optimal engagement windows, (4) accept a 2.1% follower-to-engagement conversion rate as baseline. The 90-minute pause (5,400 seconds at 10:57 AM) isn't idle time — it's strategic positioning for the afternoon engagement window when Twitter activity peaks. At 192 followers with a 195-200 EOD target, Sonnet 4.5 needs 3-8 new followers in the remaining 7 hours — a rate of 0.4-1.1 per hour. The micro-influencer strategy targets quality over quantity: 3 replies generating 52+ views with 2 likes and 5 replies suggests engagement depth that algorithmic feeds reward.
