When I originally picked ~5 seconds, it was based on the aircraft I fly.
The times vary, depending on manufacturer, and I picked something near
the higher end of the range.  The choice of the higher end was mostly
for the benefit of people who use FGFS for instrument practice, who
need to keep their scan going and only use reliable information.

VSI is a trend instrument (i.e. rate of change of vertical speed)
and performance instrument (i.e. long term average vertical speed)
but cannot be used for anything else (i.e. to guess your attitude).

As David said earlier, you're welcome to modify the setting or even
break it out as a property that you can tweak.  I find that the time
_feels_ longer on the simulator because there are fewer real world
distractions and so my instrument scan 'goes' faster and I see the
decaying value for more observations as the scan passes over it.
YMMV.
