      Hi Lorenz,

      You can certainly apply block kriging to point indicators,
      but you have to remember that the results is a composite
      probability, which is an estimate of the proportion of point
      values within the block that do not exceed the threshold
      value, whereas the block ccdf gives the probability that the average
      attribute value within the block is no greater than the threshold.
      See my book p. 305 for more explanations.

      Cheers,
