Exporting curated observations from a traditional project

I manage a few traditional projects on iNaturalist that are now large enough where we can’t export the observations from the iNaturalist project page and instead have to use the iNaturalist export tool. As a work around, we have been using the filter “pcid=true” to filter for observations that have been identified and reviewed by one of our approved curators on the project.

  1. “&pcid=true” in the URL filter means curated for ANY project right? not necessarily ours?

I am comparing the observations within our inaturalist project Herps of Texas that are “&pcid=true” versus the research grade observations that have an identification from one of our curators and the numbers do not match up:

https://www.inaturalist.org/observations?order_by=observed_on&pcid=true&project_id=herps-of-texas&quality_grade=research&subview=table

https://www.inaturalist.org/observations?ident_user_id=laspade,kvotx,jmarrugo,croelke,russellm08,sandboa,gtsalmon,cullen,wild-about-texas,texasnaturetrackers,taniahomayoun,craighensley,nathanrains,paul_crump,andygluesenkamp,toby,wendelia,caudisona&order_by=observed_on&project_id=411&quality_grade=research&subview=table

but if you look at observations within the project that are pcid=true, but are NOT identified by one of our curators, the numbers dont match the difference in the above (link here: https://www.inaturalist.org/observations?without_ident_user_id=laspade,kvotx,jmarrugo,croelke,russellm08,sandboa,gtsalmon,cullen,wild-about-texas,texasnaturetrackers,taniahomayoun,craighensley,nathanrains,paul_crump,andygluesenkamp,toby,wendelia,caudisona&project_id=411&quality_grade=research&pcid=true).

Can someone explain what I am not getting here? Or if there is a better/best solution to exporting data from our iNaturalist projects that have been identified by one of our curators.

compare:

A minus B plus C minus D = 0.

D looks like cases where a curator added an identification but then withdrew it without adding another ID.

i’m not sure how to explain C. some of these look like cases where the observer is a curator and no other curators added another identification, but that’s not true of everyh observation in this set. maybe these just need to be reindexed to push them into A or something like that?
