Ohma has shown that he can still use Water and Redirection Kata with the Advance, so on top of getting an amp he can still use some of his tool kit, and it happens to be the two that help counter Aiki (Redirection) and helps him grapple and use soft techniques (Water).
Plus, Ohma doesn't turn into a complete meathead when using the Advance. He still likes to go for joint breaks and immediate KO's via striking the throat to cut off an opponents airflow. So on top of having a definite and controlled multiplier compared to NGB Baki's ambiguous and uncontrollable one, he can still use his skill to an extent.
Ohma scales above 0.14 tons since he performed the Ironbreaker feat bu subconsciously and before he started training with his restraints off.
But the problem would be that Ohma's kit gets cut in half just for 2x boost, and he loses his entire kit for a +4x boost. Even in Advance he's liable to get entirely outskilled, as he doesn't have any feats to imply he could counter an Aiki on the level of users like Shibukawa, Baki, or Yujiro, and he just fall at out loses all grapples due to the massive lifting class difference. He has now lost all of his stat amps (Flame being speed, Adamantine being strength and durability), and he can only maybe counter Aiki
The amp is is definite, but it only appears when Baki is on the brink of losing, which shouldn't be long for reasons I will address. Also, Baki is still at 100% in terms of skill and thought process, whereas Ohma can't even use half of his katas and while he shows that he's still in a decent state of mind via going for opponents's weak spots, that isn't exactly the prowess he has in thought and strategy without Advance, he's a lot more berserk which could make him easier to read.
If he scales to above 7x Baki without his amps, while I doubt a oneshot due to the level of skill at play with both combatants, Baki is going to rack up damage like crazy, meaning both fighters would have to resort to amps sooner (Baki starts clashing his base form while in Incomplete Demon Back, and can still negate durability, win all grapples, and has several amps to help him get the edge, so Ohma amps and starts getting outskilled, and if he amps to PS, the match is decided right there.) The more Ohma amps, the bigger the gap in skill between Ohma and Baki. Baki has shown to be able to combat people immensely stronger than him Time and time again, so Ohma's biggest advantage won't amount to much here.
