After you've mastered the basics, when you've conquered Fields, Lists, and Conditions, that's the time to go back and look at your early forms. Can they be improved? Made faster? Simpler? Even less prone to errors?
The very best way to improve an intelligent form is to reduce the number of Questions needed to drive it. Every question that is unnecessary and left out will reduce the error rate, the user's workload, and increase the efficiency of the form itself.
