See User:Crouch, Swale/Bot tasks/Civil parishes (current)/Simple for more detailed info, this is just an overview.
The bot runs in accordance with the instructions (other than those on the whitelist) and created the (approximately 700) missing parishes. It notes any it misses at User:Crouch, Swale/CP whitelist#Bot missed. The rate will be the number of missing articles divided by the number of days in between the start date and mid December (rounded up).
The bot creates those listed at User:Crouch, Swale/CP whitelist, including any added that were missed on the main run that were noted at the "Bot missed" section that I have matched a name to, thus matching "Linton (Bromyard Bringsty Ward)" with "Linton" for example.
The bot runs through the entire list again to catch any new ones. We would also add any others to the blacklist that need to be.
