Time From a Physics Standpoint is an Illusion

The thing about radioactivity is that the passage of time reveals itself as counts. This is also how carbon-dating works.
The thing about counts in the real world is that it takes time to do counts! Any counting activity shows the passage of time. I just wrote 1, 2, 3 , 4, 5 in about 10 seconds.

Carbon dating does not work by counting alone. The measurement is the amount of C14 in a sample and applying the half-life of the isotope + the ratio of C14 to C12 to get the age. The amount is measured by several techniques, historlally the number of decay events per unit mass per time period. A modern technique is accelerator mass spectrometry which is an actual count of C14 and C12 (and C13 for calibration) atoms in a sample.

Exactly. That's a way of adding up all the counts (decays) that have occurred since the sample was alive.

You are still wrong. People do not count the clicks of the radiation detector for a millisecond at the top of the mountain and count for a day at the bottom of the mountain or vice versa :doh:! For the counts to be comparable they have to be counted for the same period of time and that needs a clock.

It doesn't need a clock. It suffices to have someone with a radio saying "start counting" and "stop counting."

Still wrong:

It doesn't matter. The person can just call out "start counting ... stop counting," divide the two numbers, and get the ratio of muon fluxes.

You still do not understand. That person says "start counting ... stop counting" over say 1 hour to get the first count. Now they have to say "start counting ... stop counting" over an 1 hour to get a second count that is equivalent to the first count. For example, it would be stupid to divide a count over an hour by a count over 2 hours. For the time to cancel out as you want the counts have to be done over the same time. Thus my question:

The easier method as done in the actual muon experiment is to measure 2 muon fluxes over any time period that is convenient.

You may want to read Muon Experiment again or an actual muon experiment Frisch and Smith (1963) measured 563 muons per hour at height and 412 muons per hour at ground.
