Based off a recent problem with another Bleach calc, this made me think, the accepted multipliers aren’t being used correctly. Based off the most current accepted calc, Bankai Ichigo is Mach 37 while Hollow mask Bankai Ichigo is Mach 185. That’s fine until hollow Ichigo disperses an attack that’s 10x stronger via Grimmjow fires at him(Gran Rey Cero). Which has been accepted as 10x due to being as strong or stronger than a cero Oscuras which has been stated to be an “order of magnitude” stronger than a regular cero. And both being stated to destroy Las Noches.
A Hollow mask is accepted as being an increase to all stats, which Ichigo proves when he completely outclasses Grimmjow with it in their first fight, so speed should be included. Based on the OP in the other thread, the correct speed should be
Grimmjow fight Ichigo: HHS+(mach 37) MHS(Mach 370)
FH Ichigo: MHS( Mach 370) higher at full power(Mach 740)
FB: MHS(Mach 370)
Fullbring Zanpakuto: at least MHS(Mach 370) MHS+ with Bankai(Mach 1850)
True zanpakuto: at least MHS+(mach 1850) sub realistic with Bankai(Mach 9250)
Merged hollow form: at least sub realistic(Mach 9250) sub realistic+ with Bankai(Mach 46,250).
This takes into account that when the accepted 10x multiplier for Hollow mask Ichigo was accepted, no one updated the speed to correspond with it. And given FB Bankai Ichigo has shown feats that far surpass his Bankai+Hollow form since his FB Bankai includes fullbring+hollow power as stated by Kubo, I think it’s it’s appropriate for FB Bankai Ichigo and his more powerful forms to get the 10x increase to all stats.
If that’s accepted, it would simply double the speed for FB Bankai Ichigo and his more powerful forms
