Puz,

Not to beat a dead horse again, but you still seem to be getting ahead of the data.

Especially when you say,

"It just seems to me that when finds can be made by walking about and taking grab samples, it only a matter of time before the underlying trends can be profitably identified."

I do agree with what your saying only to the extent that it may be "only a matter of TIME before the underlying trends can be profitably identified".

Perhaps glacial time, if ever!

Use more caution, my friend. Remember the lesson of Big Sky/Cloudy Sky.
