Every so often, the game just decides "You know what? Nah. All those great cards will just go to the other players. You can have the ones that give you 50 mgp." I had a run of that for three days last week.
It's the same principle as card-counting. You've gotta recognize when it's better to go for the low score. The calculators will tell you where to go for the CHANCE of the high score...
