Your over thinking this.
As you do your work you look for ways to avoid taking extra steps, motion, anything that wastes time. Such as excessive record keeping.
I use a stick edger then go to a line trimmer. One day I realized that if I started at right of the driveway and walked the property perimeter in a CCW direction with the line trimmer. I found that I wound up on the left side of the drive way. Then go up the driveway and around the house in a CCW direction and would wind up where I started at the Right side of the driveway where I started from.
I eliminated all back tracking. Which saves time. All done without an excel spread sheet.
