How far do you twist the pen?

I gave myself the first shot yesterday but wonder if I underdosed myself. The instructions say to twist the pen until the number "1" is seen inside the window. I did just that but I was confused because the lines stop before "1" showes up completly. So I ended on the last line and "1" was like 4/5 visible. Do you twist past the lines so it's fully on "1"?
