The speed you have called "the real speed" is not the proper speed of
the proton, you really think that the speed (dx/dt) where t is the time
in the lab frame is 6947c. The fact that you think "the proton rotates 
78 million times per second" shows that.

You are saying that when the physicists who are operating the LHC
know that a proton has gone around the circuit once, it has really
gone around the circuit 78000000/11250 = 6933 times.

Yes, and yes.

Yes.
