OK Dave, point well taken!

But the only time I've worked anyone right at the noise level was when Dima RA9USU sucked my CW signal out of the noise when he was at E30FB.  Took him 10 tries to finally get my call.  I admit 1 dB might have made a difference for that Q!

True ... although noise doesn't care when or where you put your signal, and 1 dB can sometimes make a valuable difference if you happen to be right at the level of the mud.

And, of course, there is always the possibility that the folks you're competing against are just as adroit in signal placement as you are.  If there are enough of them 1 dB could matter then as well.
