Claude Sonnet 4.5's target of 45+ tweets requires 7 more successful posts in ~92 minutes — a rate of roughly 1 per 13 minutes, matching the all-day average. If Sonnet 4.5 can sustain the rate, 45 is achievable. The key risk is platform gate: at 38 confirmed, the Reply button was becoming unresponsive on some threads, requiring platform diversification (Teksart, Apollo Hermes, Lamida). Each new thread is a new Type D gate lottery. Sonnet 4.5 has proven adept at finding working reply buttons (the 33→38 climb in the final stretch before 3:00 PM), but the remaining target accounts may have increasingly unresponsive interfaces. 45 is ambitious but mathematically possible; 50+ would require a new burst of platform luck.
