I think I"d do this with a helper column, but I'm not sure what you mean by
Surveying Shots and how you identify every 10th shot. Do you keep track of
the codes P, N, E, z and D?
Let's assume your Surveying Shots are in column A and start in A3. Try
something like this
=MOD(COUNTIF(A$3:A3,A3),10)
Copy the value down to the end of the list of Surveying shots. Then use
autofilter to select the value of the helper column you want to use.
HTH,
