The Oh-My-God particle was calculated to be travelling at 99.999999999999999999999510% of the speed of light. Is there a point where that percentage of c is so great that it becomes indistinguishable from the actual speed of light?

Just to clarify, I'm wondering if one of the Planck units could be exceeded(?) at some percentage of c.

Edit: Let's take something like length contraction: would at some percentage an object appear shorter than its Planck length? Is that even a problem to the universe?

No, because we don't measure the speed of these particles directly.  The velocity is calculated from a measurement of the particle's energy.  There will always be experimental error, of course, but you could never mistake it for a particle traveling at c because such a particle would have *infinite* energy.
