Arthur,

I have a question about the stones/tumbles/gems system.

It seems to me that the title of the last category is telling. Gems are precious and rare. Is this implication implicit in the system?

Personally I value gems more highly than stones, because I'm great with ideas, but poor with follow through, and admire those who can "close" as it were.

If you have implemented this form of ranking elsewhere, what kind of distribution have you found between those who earn high stone rankings, those who earn high tumbler rankings, and those who earn the gem label.

Thanks in advance.
