@Grudge - the main reason I refuse to acknowledge the "7 pieces" is because the size of the meteorite being as it is, it only being cut 7 times would suggest one of the following:
1) The meteorite broke the rest of the threads it came into contact with -- This is impossible as there would be a large gaping hole in the bird-cage, which would allow the victims to walk straight out.
2) The meteorite went mostly intangible.
Or
3) the gap between each thread is roughly a few dozen meters apart -- Again, people could walk straight out of the cage.
Also, you tried to draw out 7 pieces in the second page: http://www.***********.net/one-piece/751/7 - I counted a minimum of 10 directly on the meteorite, and there are visible lines on several of those pieces that suggest that they were also cut apart, and the pieces in the air, and further in the background are completely separate from the large chunk of meteorite presented in the panel.
While presumptuous of me to suggest, I doubt that the editors and Oda would sit down, and for 3~4 panels, draw out thousands of sheets of meteorites all closely embedded together. That alone would eat up their already tight schedule for making manga chapters.
@Sera, Scarlet, and Kinkiest - "At least High 6-C, Likely Low 6-B" For characters such as Akainu, Aokiji, and Kizaru via scaling above Fujitora works for me. Should the yonko be the same, or strictly "Likely Low 6-B"?
Also, if we're all concluded on talking about the tiering itself, we're going to have to settle the speed xD.
Low end for the Doffy Calculation = All profiles reverted to Massively Hypersonic.
High End (though I'm not sure if it goes against a rule for finding the velocity via KE): Profiles remain MHS+.
