sharpologist.com has the beard map drawing. I didn't find it very useful myself. I also found the direction my hairs appeared to be growing on occasion was not the actual grain direction. I can only assume they are curly and turn once out of the skin. I found this by feeling the direction the 5 o'clock shadow felt the most scratchy. I might be just plain strange, but something to be aware of anyway. There are those that advocate 2 off WTG and finish so yes, if that's what works for you. Try it. Won't cut it with me though. Some skip the WTG and do two XTG. There are no rules... what ever works for you. I was doing four passes on the neck at one stage (double XTG) but these days I drop the WTG on the neck and stick with three (or two as it happens on occasion).
