Verification of this Speed

[Vivi]

Ok so I just like to request of how true this is:
I am talking about Kazu from Air Gear showing to be able to open all Doors.

Look:
http://outskirtsbattledome.wikispaces.com/Character+profile+-+Kazu+Mikura

Kazu is stated as Supersonic to low Hypersonic right as you can see yet that was him with a R.E.A.D. of about 250.

However as of Chapter 323:

As you can see his Read was so high that it even hit the 5 Digit Zone and higher so possibly even 6 Digits.

Up to 5 Digits:
Lets round it up to 100,000 for calcs sake which makes Kazu's R.E.A.D. 400x as high.

Now would that also affect his Speed cause with Supersonic Speed that'd be like Mach 400 and if he is indeed Hypersonic (which starts at Mach 5) then Mach 2000 possibly even higher considering we have no exact limit of how high it went?O.o

Inconsistency if you ask me.

EDIT: Or a plot induced power boost.

dont bother trying to 'bracket' speeds in 'number form' (unless its from somthing like, for example, 0 through infinity;))

as theres always an inconsistency of sorts, as authors/artists dont make all this stuff to scale, and even if they tried theirs still inconcistencies via the nature of fiction (especially fictions avove 'street level' per say), and besides its more important to just observe how the characters are portrayed in the canon sources, and just enjoy what your reading/viewing regardless
