hybrid rules are not quite stable..

I filled in as the "manual scorekeeper" (pen & paper records of final scores) for about 10-15 matches at VCU. During that span, scores were adjusted from the real time scores in at least 3 matches. Hybrid was the most common adjustment, as refs knew they had either missed pressing the button or pressed it one too many times, etc.
Also note that there are nine refs this year, one on each corner, two on each finish line (one for balls, one for bots) and one head ref. They do talk to each other and pick up each other's mistakes more than most people think they do.
