George,
If the requirement is to dampen the interface, if it flags twice within 20
seconds. A half life of 5 seconds will not cut it.
If the task is silence about the max-suppress-time, there is no point to
give it alot of thought, just pick a value that will be meaningfull when
compare to the half life and reuse values. The max-suppress-time, only tell
you that, if you do not want to leave your penalized interface at the mercy
of the exponential decay process of half life and the reuse vlaues; then
what is the maximum time, you will want the interface to be suppressed, the
magnitude of its 'crimes' notwithstanding?
The major factors in deciding your question is 1) half life 2) penalty for
each flag and 3)suppress vlaue. We know the penalty to be 1000; so we are
left with only two variables to adjust.
Looking at your task closely; a half life of 20 seconds and
max-suppress-time of 80 is not bad.
