Hmmm.
Remembering my early training... In quality moving coil test meters this was
referred to as critical damping and not only gave the best response time but
also gave confidence that the meter needle wasn't sticking. With dead-band
damping where the needle slowed to a stop as it rose (or fell) you were always
tapping the glass because you weren't *quite* sure.
