I got some of the details wrong last week in some of the examples that I used, Jim, and I'm sorry about that. And I'm going to try to do better. One of the reasons I regret it is that getting a detail wrong interfered several times with the point that I was trying to make.
the speaker regrets it because of the interference it caused.
