I was at an ASA clinic when they first adopted the DP/DEFO rule. There were five instructors from ASA (OK). They spent the entire time arguing as how to administer the system. All of us in the audience wondered how we were to handle it, since the instructors couldn't agrre. Luckily, no college coach in any game I worked until I retired used it. Their feeling was, "I don't understand it, I won't use it, I don't want to forfeit".
Glad to see someone finally has it figured out.
