You'll be surprised by this, but I disagree somewhat.
When bankrolls are really small or prizes become really large utility becomes a more important consideration than traditional bankroll management.
If I know I can pick winnerz at 55%, but can only spare 50$ a week out of my salary in order to bet them, it becomes worthwhile to take some big risks on long shot parlays because a large bankroll gained quickly will be more profitable in the longrun.
