I think if it suits you best, ignore their markings and write your own. No point in setting yourself to have to count every inch every time you want to cut. I never use the number 1 anyway. I usually start at 2 or 3 so I am sure I am absolutely straight up and down and side to side. So for an 8" strip for instance I start at 2 and cut to 10. Never did re-mark it because I like to vary it so I'm not always cutting at the same position. If you put blue painters tape on it, you can shift it over from time to time, so you're not wearing at the same exact place every time either. Best of Luck!
