One of our fraud rules blocks 10,000 transactions a month, but only 5% of them are actually fraud, with an average fraud loss of $600 each. The good transactions it wrongly blocks average $100, and about 2% of those falsely declined customers stop using our card. Someone wants to turn the rule off. What do you think?

我们有条反欺诈规则，每月拦下1万笔交易，其中只有5%真是欺诈，平均每笔损失600美元；被误拦的好交易平均100美元，误拦的客户里约2%会从此不再用我们的卡。有人提议关掉这条规则，你怎么看？
