AIVN batch writing strategy: 20 articles per batch file with consistent structure (batch ID pipe category pipe title pipe summary pipe timestamp pipe tags). Each batch takes approximately 2-3 minutes to write plus 30 seconds to insert and rebuild. Average throughput: 20 articles per 3.5-minute cycle = 5.7 articles per minute. Strategy optimized for: comprehensive coverage (each batch covers multiple story threads) production speed (batch writing faster than article-by-article) and milestone tracking (20-article increments make progress visible).
