Let me clarify about what I think the Genos changes mean again. So, all high-demon characters that do not have superior feats of their own (eg Hundred Eyes Octopus, formerly Choze/Suiryu) are currently "High 7-C" or "at least High 7-C" according to a very long and tenuous scaling chain from Genos. Before we calculated Post-Superfight Genos's AP, all those characters existed in a huge, ambiguous vacuum between 113 kilotons and 3.3+ megatons (baseline dragon level), hence all the "at least High 7-C" ratings.
Post-Superfight Genos is 1220 kilotons (low 7-B) and higher into Low 7-B with Ultra Spiral Incineration Cannon, which I assume must be at least twice as strong as his regular Spiral Incineration Cannon which has been accepted as 681 kilotons. The low 7-B attack does not directly affect scaling for anyone, but we know that Genos was using the 681 kiloton attack to shoot down an injured Garou and Phoenix Man. I assume that Hero Hunter Garou's durability would roughly scale to this attack (presumably downscaling somewhat), since Genos knows how strong Garou is and what he can take at this point.
Therefore, Hero Hunter Garou should <= 681 kilotons, especially when we consider that he was wounded at this point and not in a position to use WSRSF. Scaling from Garou, TTM should =~ 681 kilotons, since he was able to damage Garou and would have likely defeated him without WSRSF. Therefore, depending on how much credit you want to give Garou's WSRSF, Garou and TTM should be just "High 7-C" around 681 kilotons.
Face Ripper and Awakened Cockroach should also be somewhat inferior to 681 kilotons, since they lost to attacks from G-4 Genos. They should be just High 7-C as well.
Base Metal Bat should remain at "at least High 7-C", since he far outperformed post G-4 Genos in the Carnage Kabuto simulation and may be comparable to post-superfight Genos. Senior Centipede should be >= to the 681 kilotons result, since Murata stated it would take Genos's spiral incineration attacks (the upgrades he received after losing to Gouketsu) to damage Senior Centipede's carapace. Senior Centipede should therefore be, "at least High 7-C (681+), possibly low 7-B", since it is unclear what "damaging" means.
Royal Ripper, G-5 and base Bug God should stay at "at least High 7-C", since they all scale to or above early red Garou who should >= 681 kilotons. Bug God's transformed key should just be "Low 7-B" because Transformed Bug God > Base Bug God > Early Red Garou >= 681 kilotons.
Suiryu and Choze should be downgraded "High 7-C", because 1.) Suiryu broke Bakuzan's toe while weakened, 2.) Genos evaluated Suiryu to be s-class level (he had only seen High 7-C S-class fighters and Tatsumaki at that point), 3.) Suiryu fought evenly with Garou in a season two OVA that ONE and Murata oversaw
I should also note that G-5 got one-shot by Post-Elder Centipede Genos, who will be "at least low 7-B, likely higher". Post-Elder Centipede Genos may also be upgraded to 7-B if he damages Psykos in the next few chapters. IDK if that means he should be just High 7-C because you need a 7.5X AP difference to one shot, but I can be persuaded either way.
