Systems often tout their high win rate but more important  is that the system generates a strongly positive expected value because the Win/Loss Payoff Ratio easily overcomes the win rate. Look for a distribution with big wins, small losses.

In old England if you could get 12 of your friends and neighbors to vouch for you, you could be exonerated of malfeasance. The idea of a jury came from this. Could you gather a dozen people to vouch for you today?
