Interesting discussion. I would challenge people to do this experiment. Go to what you think is a random spot in your field. Take 13 core samples in the shape of a cross 2 ft apart one in the center and 3 on each side. Test the individual core samples. Don't tell the lab what you are doing. You will learn a lot.
What’s it going to prove? Nothing but it gives you another data set.
Whats your challenge?
What is the purpose of this data set?
"If I was wanting to check lab accuracy I would sent 1 know sample"
Why then would you not tell the lab what your doing if your not checking them?
"You will learn alot"- what are you referring to?
"Statistical relevance depends on the consistency of what your sampling also."
I agree, that is precisely why you take more cores than less. Thats why you create very detailed zones to direct where you sample.
