Judy,
I think his question is how many SHOOTERS quailify for the world from Bedford, is it the top 20 or 25?

The next thingthat should be cleared up is that ties are counted as one place, which is not in the rule book and should be added.

The SHOOTERS qualify by their SCORES. Ties are counted as one place.
If you have the same score as another shooter but less 11's then you are one place under that shooter. Ties are same score, same number of 11's.

Hope that helps.
