Fortuna And Other Arabic Parts

In our KP System discussion forum, we are having an intense discussion on the fast moving point 'Fortuna' (also called Pars Fortuna or Part of Fortune). Shri K. S. Krishamurthi, the inventor of KP System, mentioned about Fortuna in the second reader, but he really didn't given much detail. The application and examples are also missing. While doing some googling, I found this article very useful. Please check it out.
