The only thing we can argue is that she made her bubble shell in the time-frame, but the shell is NOT her arm length. We can even argue that she reacted and began her defense before the lightning was triggered by Nami.
With this, there would be absolutely no support for MHS combat speed and travel speed for pre time-skip characters, and no support for MHS travel speed for the ENTIRE verse. Kalifa's bubble shell does not scale to combat speed
This would mean a speed downgrade to Hypersonic+ for all characters during and after Water 7 arc.
High tiers and above will keep MHS combat and reaction speed via scaling to Doflamingo, since he performed a MHS feat by slicing a meteorite apart.
Unless Kalifa has MHS+ reaction speed (she witnessed Lightning falling down from a few meters away and acted upon it), this downgrade must happen.
I recall Khalifah being able to anticipate the lightning before the bolts were protruded, seems she should be a lightning timer rather than having lightning speed reaction if anything and even the name was a give away of the attack. I can see this being more reliable if we don't use this lightning reaction. She would have evaded before the thunder could strike, it wasn't exactly point-black at all. And she couldn't even react to the mirage's movements with the same lithe of reaction.
@Addrash - the 2nd case can be argued as "not real lightning" due to the nature in which the attacks work and where it comes from, though it could actually be lightning-speed, either way, it's still possible that Kalifa is MHS regardless due to the first feat (her reacting to Lightning from a few meters away is already Mach 190 minimum, potentially higher).
If that's the case then why couldn't she react an even slower lightning? The point was the balls were much slower and Nami's not MHS, so she should be able to evade her lightning balls with that agile of a reaction, so it might be a discrepancy.
@Ant - true, especially since the "mach 190 reactions" is only from the last possible time in which she needs to defend herself. her reaction speed could be considerably higher. So now I believe that we can maintain MHS One Piece since we've mostly solved the problem (no extra work! Yay), but I am curious of one thing:
Do you know exactly why characters are listed as High Hypersonic in Water 7? I looked at the calculation and only saw that it was Mach 9, which is Hypersonic for Zoro's speed.
Unless they scale to CP9 members, High Hypersonic is not supported. Zoro and Sanji would need to be upgraded to MHS (Sanji being too fast for Kalifa to react and both being capable of fighting the higher tier CP9 members and winning, for example).
@Ant - i made the appropriate changes to those three characters, so now i'm curious about what this means for characters like Chopper, Franky and Nami, who could keep pace with CP9 members in some cases.
I am not sure about Nami, but Chopper and Franky being MHS seems consistent.
I need to ask something regarding the speed of Rob Lucci:
Do we assume that his speed is multiplied as he possesses a Doriki that is 5 times superior to the lower tier CP9, and 6.35 Kalifa's? I'm sure that would be calc stacking territory, but if not, we'd have Lucci at Lightning speed. Luffy himself could blitz Blueno from over a dozen meters away on several occasions in Gear 2nd, while Kalifa could react to Lightning at a much closer range.
I'm not sure if this is the case, but it's worth asking regardless (it is the wank speaking).
I'm going to message the rest of the Calc group to come over and give input on this thread and the calculation i did regarding Kalifa's reaction speed.
