I set out to see what I could do in a Marathon of Frenzy and I found out it was about 21 hours. I lasted 20 hours and 39 minutes before I lost all my men. My final score was 2,504,477 points. I'm working on uploading all the footage now to youtube so I can post it here.
I can honestly say that was about the most grueling experience of my life. at one point I had extra men to the 5th row, and someone told me I had 126 extra men! I'm glad I went for the record and I'm proud of my score! I will post more about this attempt when I am more recovered!
