I think people reviewing with 'perfect' have not run it long enough. I ran into problems where the bot broke at ferox cave a few times, it would persistently run between the fountain and the bank, and other times would spam my teleport tabs burning through them (more detail on the discussion thread).
I am able to run bot sometimes for 15 hours before it breaks, and sometimes only 1 hour. The bot author does not respond to issues, which has knocked off a star rating.
