We currently are not using SRDF/A but plan to in the future.  I have been reading up on this product and have also taken the Business Continutity training course but I am still having some difficulting understanding how the delta sets work in relationship wit the cycle times.  Was just looking for some help/clarification on this.  I get the 4 types of sets so if, I leave the minimum of cycle time with the default of 30 seconds how will this work?  Does the capture set take the full 30 seconds and then does a cycle switch or does it only take how long it needs to capture changed data?  Also, is the Transmit and Receive considered one delta set?  Any help on clarifying this would be appreciated.
