The listing of the program was based on its accuracy in duplicating the delivery times of many different arrangements that had been configured and timed by the old Central Sprinkler group (my recollection is that the program demonstrated its accuracy for nearly forty tests that had been conducted). All of the test arrangements were done with 'tree' configiurations. No 'looped' systems had been included in the Central testing, and, thus, there were zero results against which the accuracy of the program could be tested. The program is capable of calculating a simple looped system, but the listings that were granted were based on the tree testing and the accuracy of the program results. Hope that this answers your question regarding the listings or lack thereof for looped systems.
