I have uploaded a new version of the script.

Now the script does the processing of the archive.
But you have to tell the script if it should process the current database or the archive.
Usually you will need to process the archive only after you have moved new "old" items to the archive. So you can control ist using a flag.

I have also added two more graphics.
So you can see how long usually it does take to process (duration till completed) your tasks (0-1 days, less then 8, less then 30, less then 90, less then 180).

There is also a graph that show how old your current active tasks are. (using the same logic as above)

Hope this helps to find out a bit more about your working with OmniFocus... and that the script is not too buggy ;-)
