Not relevant.

Completely relevant - it's the basis of how the devices are designed and
how
codes are arranged.

I highly doubt anyone ever seriously concidered the implications of being
within 500 feet of a million people -AT ANY ONE TIME- since it would
be physically impossible.

Downtown Manhattan.

Dividing a 500 foot circle into a million discrete areas gives each area
around a bit less than 11 inches on a side.

Not a chance.

Given trips to malls, the supermarket, etc. in metro areas, it wouldn't
take long to have been exposed to a million people within 500 feet.

The relevance is "at any one time".

Not hardly.

Only having that number of people AT ONE TIME is relevant in that ONLY then
can they set off your device.

With a probability of one if matching devices exist.

If you have a million devices and 1 match, hand those to a million
people, randomly select 500,000 people from the group to stand next to
and the probability is .5.

Select 10 out of the group and the probablility is .001.

Select 1 out of the group and the probablility is .000001.

You consider probability to be adolescent?
