The expanded library is great. Keep it up!
MathProf's "Fluctuations" article struck a chord. There's no sound reason not to treat advantage play as just another investment, and conceive of one's bankroll accordingly. Yet it's hard to make the mental adjustment. My stock portfolio can and does gain or lose as much as $5,000 or $10,000 in one day. If I were to lose that much gambling in a short time, or ever, I'd probably have a stroke. This makes little sense. Call it our Puritan heritage nagging at our minds. Investment is frugal and prudent, while gambling is frivolous and foolish.
As said in a great article I was reading recently, poker and casino games are characterized by stochasticity, meaning random outcomes over a known probability distribution. The stock market does NOT exhibit stochasticity. Instead, your fortunes are determined by random events over an UNKNOWN probability distribution. Gambling is better, because it's more predictable!
