I did some analysis on CVCX regarding my last trip. There is no doubt that I should have played the double deck even if the pen was 50 %. I got c-score of 42 on the method that I was playing on double deck. I was spreading 1 - 30 and getting away with it. I happen to get unlucky and stopped after a few shoes. That was so much better than the c-score of 17 I was getting on 6 deck. I really need a laptop to bring with me on these trips.
