   Due to the small number of unknowns IAC HQ has, some
 folks that have been around for a while may well have a copy
 of most of the unknowns.  Therefore, they have an advantage
 over the others that do not have access to them.
 Publishing the unknowns that exist and have been used before
 would be one way to level the playing field. 

 I do agree however, that a true 'unknown' should be unknown
 to all the pilots.  Given the large number of figures usable
 in an unknown, the combinations of sequences are quite large. 
 Maybe we can agree on some small set of unknows that could be published
 that are sort of 'generic' unknowns that are typicall for each
 category.  This would IAC members that move up to a new category
 a place to get some 'starter' unknowns just for practice. 

 I have a set from prior contests and I like pulling one out
 before a practice flight of a known/free and I then fly the
 unknown at the end for grins and practice.

 Does HQ continue to add to the pool of unknowns or are they
 kind of static??  Also, how many unknowns does HQ have for
 each category?
