Mine are more like long tight zig zags going up and down about five feet centered roughly vertically on the wall. I work it from top to bottom on second pass and backroll when I have two or three of those. I'm not saying the other way is wrong C7, I'm simply saying that the big W/M method is not that bad, more important is backrolling technique. If you can't roll fast enough you might want to do a not so big W to prevent dried edges.
You're a fun fellow C7, I just think you fret the small shit too much.
