Are you claiming that the real speed of the protons in the LHC is
  Vr = 6927⋅c ?

 Absolutely.
 That's what I said.

 Since it is you, Doctor Richard Hachel, i will assume you are serious.
(Nobody but you could seriously make such a ridiculous claim.)
 You are obviously ignorant of how a synchrotron works.
 The protons in the LHC are moving around a ring with
circumference 26659 m. The ring consist of straight
stretches and bends. In the straight stretches there
are eight RF-cavities which accelerate the protons.
In the bends there are magnets which make the path of
the protons bent. The protons will radiate some of their
kinetic energy as synchrotron radiation (light with a special
spectrum) in the bends, and when the synchrotron is in steady
state at peak power, the energy gained in the RF-cavities will
be lost in the bends.
 In a RF-cavity there is an electric field which is changing
direction sinusoidally all the time. The protons are moving in
bunches, and a bunch must be at a RF-cavity exactly at the time
when the electric field is at peak value in the right direction.
Since there are many (N) bunches in the ring, and each bunch are
going around the ring many times (M) per second, the frequency
of the RF-field in the RF-cavity must be a multiple of N x M Hz.
The nominal frequency is 400.8 MHz, but this is finely tuned
depending on the speed of the protons.
 The point is that the speed of the protons is very precisely known,
and the measured and real speed of the protons is the same.
 You are claiming that the protons are going around the ≈ 27 km ring
≈ 78 million times per second.
The real value is ≈ 11.25 thousand times per second.
 Don't you think the physicists at CERN had noticed the difference? :-D
 But maybe you were joking.
In that case you had me!

CERN physicists are doing their job.
We have accustomed them to working at classic relativistic speed (useful but false).
So it makes sense that they find the speed they expect.
I tell them that the proton rotates 78 million times per second,
They tell me no.
I tell them that to be consistent you have to measure things with a single watch, and that measuring the departure of the proton and the arrival of the proton with two different watches (in this case, the lab watch that counts the revolutions is TWO watches) can only lead to measuring speeds incredibly lower than reality.
Only the proton itself has the correct watch, because it, in its frame of reference, accelerated or not, is invariant.
Now, if we want to know the real speed of the proton, we must know its momentum in an instant of its journey.
Physicists will necessarily find p=m.Vr, and not p=m.Vo.
Vo is a decoy caused by universal anisochrony.
This is not the true particle (or rocket) speed.
