Never heard of the scoring technique - that's a good idea that everyone should know about, IMHO.
Thank you so much for pointing out that you can listen to KOA on the computer.
KOA is the only station in town that covered a protest I helped organize against the RMN & Denver Post back during the 2000 election (They lied in their election guides, and omitted candidates). KOA's early morning news crew is the tops in my book.
Even after switching to Dish Network, I kept my big dish just so I could get KOA. A really good station.
