This principle is of course true. Another principle us that if you do make mistakes, and the other guy makes fewer, you can lose. In subjective areas telling the difference can be hard. Some are inclined to err on the Picard side (it wasn't my fault) even when it was. Others lean towards the opposite (I could have done more). In many cases I suspect it's a combination of both in play. The real skill may be in telling one from the other.
