It probably was a lot of work to set up the script and then to make tweaks to the script, but now that it is running, it probably does not take as much work, unless some bug/glitch (or bad results) ends up getting spotted.
The script will probably just skip through error I don't think it's collecting and sorting after ( depends on DK actually), so If its what I'm thinking then spotting error can be easily neglected beside manual is prone to errors itself
