It's more than a little lag <G> - particularly on those occasions the 
lower level is nearly 3 dB low to start.  I'm looking forward to the 
next one.  Perhaps the update rate should be adaptive - fast for the
first couple seconds of a transmission and then slowing down after the
power has had a chance to stabilize ...
