Thanks for all the recent enhancement Jun, this is very exciting. I  
have been following the conversation sort of, in the midst of getting  
a grant submitted. In response to some things from today:

I agree. Having the default be alpha does increase room for error and  
adds inevitable multiple keystrokes at each ranking. But I don't know  
how hard this is to change.

In the absence of a ranking from the previous month, the best default  
is by age-sex class, with different rules for each, in this order:

1. Adult males, in reverse age order (youngest to oldest_
2. Subadult males, in age order (oldest to youngest)
3. Adult females, alpha
4. Juv males, age order (oldest to youngest)
5. Juv females, age order (oldest to youngest)

I hope this helps.
