Okay. My first stab at 8 tables, 54 rounds just finished. It seemed pretty good, but I think it would improve if I spent more time on it. ... It took about 3-hours of compute time. One thing we can learn from it is that, if you chose to change how you organize, no one would play with anybody less than 4 times or more than 6 times out of the 54 games.
