Here is a question for you, how do we know who wins elections from only tiny amounts of returns?

You're still not understanding my point, and I'm still not sure if that's deliberate or not...
I'm familiar with random sampling and am not sure that even this argument of yours will work here...
Variables which would seemingly prevent the arrival of an accurate dating of the pyramids from a random sampling within an
unknown
population would include but are not limited to these two:
1) Again, sampling taken from an unknown population. You're analogy about who wins elections confuses me a little because a) you're saying that
it's "tiny amounts of returns" and b) this is a sampling within a
known population. But lets take a look then at the
2004 voting numbers, for the sake of this argument. Basically (according to that site) of
the 216 million people in the US who are of age to vote, 142 million are registered, and of those, 126 million voted. So essentially
we have a
sampling from a known population which shows that 89% of the registered population voted; point being, that hardly seems like tiny returns. So
what did you mean by this?
I believe the question I presented regarding the testing (or non-testing) of all samples is related to sampling bias. Please read: taken from
HERE.

Validity and Sources of Error
The distribution of values in any sample, no matter how it is selected, will differ from the distribution in sample chosen by chance alone. The larger
the sample, the more likely it is that the sample reflects the characteristic of interest in the target population.
However, there are sources of
error not related to sampling that may bias comparisons between the sampled units and the target population. First, coverage error (selection bias)
may arise when the sampling frame does not fully cover the target population.
bold mine
So it seems we have a matter of selection bias to contend with when looking at the samples taken for the radiocarbon testing of the pyramids.
2) The dating of the pyramids, particularly that ascribed to Khufu, focused on matter found on the outer most layers without any (AFAIK) testing from
matter within the pyramid itself. Now taking matter from within the pyramid would require some tunneling or slight dismantling which of course (and
understandably so) the Egyptian authorities would not allow given the destructive nature of this scientific investigation.
So again what we have here with regards to the dating of the pyramids is incomplete and should not be used as hard evidence. And regardless most of
the dates arrived from the first 2 tests of Khufu's pyramid are older than Khufu himself.
Could the results from both tests, which were from samples taken off the outer layers and not the inner, but also having shown some dates within
Khufu's reign, if used in conjunction with what the inventory stele says, be indicative of Khufu having actually made repairs to the GP and not
necessarily having built it?
But again, I have yet to find all the results from both tests. Mainly I want to see from where exactly the samples were taken and how many.
Even having gone back to read
THIS it sounds to me to be very wishy-washy. I mean
even they say on the site:

In other words, it is the old-wood effect that haunts our dates and creates a kind of shadow chronology to the historical dating of the pyramids.
It is the shadow cast by a thousand fires burning old wood.
Doesn't sound too confident to me.
