Related/meta question: despite the increase in YC cohort sizes, has anyone else noticed a sharp drop in the number of Launch HNs / YC Startup Launch Announcements on HN?

EDIT: Checked the data and yep, there's a drop: https://docs.google.com/spreadsheets/d/1EBcI3Jm2I9Kj_JMGyRnN...

BigQuery:

    #standardSQL
    SELECT TIMESTAMP_TRUNC(timestamp, MONTH) as month_posted,
    COUNT(*) as num_posts_gte_5
    FROM `bigquery-public-data.hacker_news.full`
    WHERE REGEXP_CONTAINS(title, 'YC [S|W][0-9]{2}')
    AND score >= 5
    AND timestamp >= '2015-01-01'
    GROUP BY 1
    ORDER BY 1
