If we got 1000 for every flap, then for 3 quick flaps in a row,
theoretically, we accumulate 3000. If Suppress value is set to 2000
then after those three flaps we got our interface suppressed. Now
penalty starts to decay exponentially by simple law
CurrentPenalty = StartPenalty*2^(-t/HLife) (it halves every HLife time)
Interface become unsuppressed when CurrentPenalty hits ReuseValue.
Now, half of 3000 is 1500, and thus, by setting Half-Life to 30 secs, and
Reuse Value
to 1500, we could get close to desired result.
dampening 30 1500 2000 100
