I have used a couple of different programs to create indices based on the type of game I will be playing and seem to be coming up with different numbers which also come up different than some of the Illustrious 18. How should I decide which indices are correct? Was Ill. 18 based on a 6D game? Most of the games I am playing are DD. Which would be a better source, Bj-strat or the strategy file for DD included with Powersim?
