When I query the g_us_rel_doc table for patent 10204147 I only see 1 entry for a related-publication. This aligns with what appears to be in the bulk data XML. 

My question then is where does the Patent Center get the child continuity data from as shown at the link below?

https://patentcenter.uspto.gov/applications/15091563/continuity?application= 

Maybe I'm mistaken, but I thought that the us-related-documents section of the bulk data would include all the continuity data?
