That's not quite correct. There are 2 very different things called control. What you're referring to as "control time" actually falls under effective grappling which is the first criteria. But inside that first criteria, since it is considered cumulative, it is scored at a much lower rate than impactful effective grappling.
What you're conflating it with is "octagon control" which is just keeping the center of the octagon. That's the third criteria.
Scoring criteria linked below:
It specifically goes into using those positions to achieve impactful offence and preventing your opponent landing their own. If you are just holding someone down or against the cage, you aren't being scored under the effective grappling criteria if they can still attack you back. It's an old hold over from back in the day that we reward the fighter on top.
This line used to be in the criteria but appears to have been removed, so maybe things have changed:
"Top and bottom position fighters are assessed more on the impactful/effective result of their actions, more so than their position."
If so then it may be a return to the older criteria with top/cage control being sufficient to tick that effective grappling criteria.
As per the 2022 criteria you should have been able to negate that by striking off your back and throwing up subs and being the more effective in the grappling phase. Unfortunate if it's the case, but would probably make me agree with you.
Current criteria for grappling below minus control time.
Judges shall evaluate Mixed Martial Arts techniques, such as effectivestriking/grappling(Plan A), effective aggressiveness(Plan B),and control of the fightingarea(Plan C).Plans B and C are not taken into consideration unless Plan A is weighed asbeing even.
Effective grappling is assessed by the
successful executions and impactful/effective result(s)coming from: takedown(s),submission attempt(s), achieving an advantageous position(s) and reversal(s).
Dominance in the grappling phase can be seen by fighter s takingdominant 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. In the absence of dominance inthe grappling phase, as set forth in paragraph 3 of the promulgated rules, to be considered dominate,there must be a singularly or in combination, some types of submission attempts, strikes, or an overwhelming pace which is measured by improved or aggressive positional changes that cause the losing fighter to consistently be in a defensive or reactive mode.
