I had to wait a bit until the chart for January 2023 was out to confirm the time period tracked by Publishers Weekly since their monthly chart for December 2022 indicated a five-week period ending December 3, 2022. Having the January chart now confirms that the period tracked actually occurred from December 4 to December 31 (four-week, 28 days).
One more thing, I am pretty sure I checked the trade paper frontlist Top 25 every week, but I did not see Dragon Ball Super Volume 17 making it onto the weekly chart. If you manage to see it chart, please let me know.
