You need at least three flaps to trigger dampening.
i guess you really need to look at that pdf.

"Better Algorithms" -- http://www.kotovnik.com/~avg/flap-rfc.txt http://www.kotovnik.com/~avg/flap-rfc.ps I didn't publish that one because I wanted to compare that with penalty-based dampening on historical (pre-dampening) flap records, but then got distracted by other projects. Preliminary data (from frequency analysis) indicates that "unwarranted downtime" (defined as suppression after the last flap prior to entering stable state) is reduced by a factor of 3 to 4 compared with penalty-based algorithm tuned to produce the same post-dampening flap rate. --vadim
