... • Protons has a “spin” that can be either “up” or “down” relative to the direction of the magnetic field • If radio waves (FM) hit the protons, it can cause it them to flip from one spin state to the other at a frequency that depends on the strength of the magnetic field • These spin flips result in ...

It appears to me that the criticism is rather sophistic, because if the average is an exact integer that does imply that every measurement gives an integer. ...
