I disagree.
The 6-C reasoning was before it was pointed out how outmatched Akainu was in power against WB, and before we thought to scale each Admiral to at least 1/3 of his PL for collectively stopping one of his quakes. There wasn't a significant enough reason at the time, hence why they were "likely" (they scaled FAR above the High 7-As, but below WB who scaled 6-C), especially since Akainu stopped an attack from WB like ONE time (entirely possible if he's at least 1/3 as strong as him, especially when he had leverage).
WB was flagging in stamina due to his injuries, yet he still yeeted Akainu almost like nothing. Akainu's damage to WB can only really be attributed to his DF power ignoring durability because... duh magma is going to evaporate flesh and bone upon contact.
They should remain Low 6-B flat. Reasons being WB overpowering Akainu quite a number of times, Akainu only having one instance of actually stopping an attack from WB (he had leverage and a 3x difference isn't massive enough for WB to easily whack him away), and the damage inflicted by each 3 Admirals (actually, Aokiji never hurt WB lol) can likely be attributed to dura negating properties that each of their DF has. And once WB finally got his hands on one of them, he basically 2-shot with a hole in his chest and missing a chunk of his skull.
