Yeah, read the presentation several times, thus the short penalty times, and probably high thresholds.
The idea for me is to limit the harm of excessive flapping while not being paranoid. I've had a customer lose a lot of connectivity for 30 minutes after 3 or 4 flaps. I figure 5 minute ignore after about 10 flaps in a 10 minute period.
