This "make a second draw" approach would also let you tune how often you saw the "bad" articles. That is, if it's a bad article, then flip a coin to see if you should make a second draw. Repeat if the new article is bad, but never make more than N draws. Someone with time on their hands and a statistical bent could compute how often "good" and "bad" articles come up as a function of the ratio of good and bad articles, the coin flip probability, and the limit N. --scott On Aug 22, 2013 10:47 PM, "Lars Aronsson" <l...@aronsson.se> wrote:
