For the fun of it, I took the Trackjack casino data base and created seven XY charts plotting penetration versus Basic Strategy advantage. These charts provide a quick glance at the current state of the game in different geographic areas. Of course it would be more interesting to look at such charts over time. Links to the charts follow:

All U.S. Casinos
All Nevada Casinos
All Mississippi Casinos
Atlantic City
Las Vegas
Reno
California
