I'm not even the guy that keeps bringing up High 6-A. I'm just saying that whatever we rate normal Gear 5th Luffy should be what Awakened Lucci should scale to AP wise. Whether that's 6-C or High 6-A, it's whatever.
And besides, High 6-A is huge scaling tier, you can have people like the Scabbards and Jack (who downscale by a lot) be High 6-A, up into the Yonko's themselves who in certain forms upscale from the High 6-A calc.
So it's not one static value (technically it is, but in practice it isn't), but more of a range. If the scabbards are a 10, then the strongest High 6-A's are a 100. Lucci could still be in that High 6-A range and still not be Yonko level (like 70 for example). Don't take the numbers literally lol.
