Jeff,
Your picture shows a blade with FAR too much camber for smoothing purposes. It needs to be very slight indeed , in the order of a few thous of an inch , which you get by pressing harder alternately on each side of the blade when honing. You also need to reduce the sharp corners a bit -you can use a stone for this.
Loren has it right when saying “a subtle scalloping …..”
I want to see a large surface , like a dining table top, that has been planed with a blade that is dead straight (plus corners reduced): there will be marks left of an unacceptable kind, for sure, and they will come to light when the polish goes on or the wife/ girl friend/client takes delivery…..
P.S: you still get a full width shaving when there is a camber as I describe, except that the edges taper to almost nothing.
