hi all,
it's pretty cool to see this topic in the magazine.
here is a post i made a while back on the topic, with some discussion that went on. the first post i made in the thread below was a little off, scroll down to the revision i made a few posts down. there is also some good discussion there from some folks overseas on using exact finish distributions to better understand the variance involved.

it's good to see in the article the author used finish distributions, as this gives a little bit more info than using just ROI & ITM. anyway, in SnG practice, i ran into the a lot of limitations in using this. for one, it essentially forces you to play in sets rather than continuously. if you are 8-tabling or so you will often be playing across 2 buy-in levels, which sometimes makes it hard to adapt. this problem gets worse the more tables you add. also you need to set a floor for the BR (and buy-in level) so that you don't get stuck playing micro-limit sng's during a bad run.
of course the other catch 22 is not knowing your ROI for the levels in which you are taking a shot. with a large sample size at multiple limits, however, this is the best way to ramp up a small BR or to rebuild a BR up to a level after cashing out or sitting out for awhile.
