>From an operational standpoint I suppose it is useful (i.e., the
segments filling up when you turn down the gain) so that you can
adjust it visually to the approx level of the background noise by
reducing it until the flickering stops. 

Probably everyone adjusts RF gain by ear though; I mean those who
don't just turn RF gain to max and leave it there.
