Chris,

Thanks for helping clarify my problem. I want to find the set of discrete hits that gives me the best coverage (if that make sense?).

In your example above (ah the beauty of acsii graphics) I would like to pick the two shorter examples as combined they give me a higher overall coverage.

I apologise for any confusion that I am causing - I am having a bad day - too hot and sticky in here!

A.A.
