Dennis, one thing I'm doing to explore this "history in history" concept - maybe you've already done this - but I'm taking the announced history and running the last draw from that history again. I guess what I'm getting is the counts of the best "Announcers of the Announcers" - the AA numbers
So, I took 5-8-12-16-20-28-38-42 and run them on the 49 3 number announced draws. Maybe if you keep going through these iterations you could narrow in on something.
I guess you could also do this for the 170-2 number announnced draws.
Draws 148 and 315 are interesting
