Do you not get that the whole point is that this isn't consistently the case and that Ichigo is
CONSISTENTLY BELOW MACH 500 even in perception speed?
Please man, read the OP it's getting tiring, you can't have someone consistently be below an attack and then try to scale them to the attack because of one scene where it's very clearly inconsistency and, as the OP says:
And Ichigo's percetion is < Mach 500 via everything already said in the OP.
The OP even has an example of Ichigo
failing to perceive the mach 500 in the most blatant way ever
You can't pick and choose whatever agenda you wanna follow. Ichigo ADMITS he couldn't perceive the mach 500 retracting but you are trying to scale his perception speed to something twice as fast? Be so for real.
