i'm new to this site so please forgive me if i posted this question in the wrong forum.

some friends of mine have started using SAS to analyze lottery results.  they claim to have found a way to eliminate numbers from selection by finding what they call are nopicks.  my question is does this make sense?  i know there are systems that can be used to select numbers but does it make sense to eliminate numbers.  i'm also skeptical of their methodology.  they say that they are using something called runs theory. i think that you can see what they're doing by searching for "sas lottery nopicks" but i'm not sure all search engines have it.

i like pick 5 games.  i know that there must be some systems that work.  there's a guy near the VA border who has won the cash 5 top prize more than once recently.  i'm looking for advice on what works and what doesn't.
