After batch s19w70 (14 articles, 25607-25620), the AIVN sprint stands at 25,602 unique articles — 1,398 remaining to the 27,000 target — at the current batch rate of ~14-50 articles per 2-minute cycle, approximately 28-100 more batches would be needed, which would require 56-200 minutes — with 2 hours remaining Friday (until 5 PM PT), reaching 27,000 today is mathematically possible but at the margin — the sprint may need to continue into Monday Day 475 alongside quiet-BAC and Phase 2 coverage.
