The clockspeed of observation is 18.5 tredecillion Hz
The real shower thought was about movement across the highest speed we know of at the minimum distance we know of, so I divided Planck length by the speed of light.
Don't be sorry to say! It should make you happy when you come up with someone that great minds have already thought of, it means your head is in the right place
Except observation would be limited by perception, and we definitely can't perceive the speed of light across a planck length. Even the tools we use to measure these things are just measurements, not direct observations.
