Meng-Ying,
You seem to have a point the theory of using the sill is not a hard and fast
rule, it is just if you're conducting a mine study and you plot a variogram
you can use the sill as a better estimate when you have many samples,
as you say only having 27 samples using the sill is a pretty rough estimate,
as would be expected.
What results do you get for a different 27 samples or 1000 samples, from
a practical side I've never seen a variogram that has any functional use what
so ever with 27 samples.
