- But mn wasn't talking about *independent* review teams. He was talking about
- adding more people to a team. In this case, I suggest that the amount/number
- of errors detected per person added to the team decreases rapidly for team sizes
- beyond four or five.

- I agree with dg completely. I do suggest, however, that significantly superior
- results will be obtained from 2 completely independent review teams of perhaps
- 3 or 4 people than a single review team of 6 to 8.
