Why six days? Is there a one day run?

If I could hold it longer, it would be better. It works quite well when people learn new concepts and try them out at home or at the office or other situations. They are able to experience the workshop in real life and not just theoretically. In the US and Australia, I have offered the workshop but as one day affairs because people are too busy to commit to 6 days. Strangely enough, it works quite well too as former attendees can attest.
