Impact, dominance, and duration are the equation for scoring 10-8 rounds. But I agree that those are fair guidelines for determining effectiveness also.
Not sure if you are trying to intentionally misrepresent the Unified Rules of MMA or if you misinterpreted them yourself. The underlined sentence above has absolutely ZERO to do with Octagon Control Time being a meaningful stand alone metric. It's an example of effective striking causing the person being struck to lose control and or ability, E.g. The Chicken Dance.
And under the "prioritized criteria" section.
Successful execution of takedowns, submission attempts, reversals and the achievement of advantageous positions that produce immediate or cumulative impact with the potential to contribute to the end of the match, with the IMMEDIATE weighing more heavily than the cumulative impact.” It shall be noted that a successful takedown is not merely a changing of position, but the establishment of an attack from the use of the takedown.
And under the "Dominance" section of the UR of MMA.
Dominance in the grappling phase can be seen by fighters taking dominant positions in the fight and utilizing those positions to attempt fight ending submissions or attacks. Merely holding a dominant position(s) shall not be a primary factor in assessing dominance. What the fighter does with those positions is what must be assessed.
Effective grappling is dominant grappling to a lesser degree or shorter duration. Did you consider any of Gordon's hugging to have fight ending potential? I did not.
Without any sub attempts, back takes, or other superior positions that lead to 1 way striking; that 4 minutes of control time doesn't fit the criteria for effective grappling, it looks like an effective way to stall though.
What I saw, at least in rd 3, was Gordon locking his hands around Paddy w/o genuinely attempting to advance towards a finish. Instead of trying to keep it out of the hands of the Judges, he prioritized putting it in the hands of the Judges. I would have taken points from him in that round if that were allowed.
