Jun (Karl please read also and provide any feedback),

A few more thoughts about ranker after several conversations between  
Jeanne and I.

Perhaps the best way to describe the hierarchical relationships  
between rank types is as follows:

ALF is the "master" within-female ranking. ADF and JUF (juvenile  
females, not a currently designated rank type, but it should be) need  
to be derivable from ALF and consistency must be enforced between the  
relative rankings in each.

ALM is the "master" within-male ranking. ADM and JUM (juvenile males,  
not a currently designated rank type, but it should be) need to be  
derivable from ALF and consistency must be enforced between the  
relative rankings in each.

ALL is the ranking for both sexes combined. We do not want to enforce  
consistency between ALL and ALF or ALM. The within sex rank types and  
the ALL ranktype are really two different categories and there is no  
clear hierarchical relationship between them.

The rnktype FYM should be deleted. We will not population this  
rnktype with the data available.

At some point in the future there may be rnktypes that need to be  
derived from ALL but this is not obvious to us at the moment, so ALL  
is not at the top of a hierarchy in the way that ALF and ALM are.

I hope this helps, please let us know if there are questions.
Susan
