Define "proper" please. Depending on what the selection criteria are and
where one is looking, the numbers vary.  The Mice&Men numbers indicate
upwords of 75% of the delegations are flawed. My numbers point to about
55-60% of the delegations have some errors.  On a bad day, I'm surprised
the thing works as well as it does.
