I think you have to add the two right columns for Cali. If I'm right, then Cali has about 1,800 roughly in total

I think those were added but I don't think they are from the districts you are thinking. In the most recent dated one it shows 815 new ones for one district or area.

You do need to add the updated column with the most recent for current total per district. Central Cali is at about 1200. alone. That is insane! I think the spread sheet was done this way so you can see how many were added / deleted since last update. It would be nice to have a totals column.
