cam timing

[s13eater]

here's a question for you, i'am fitting a new timing belt but i'am a bit it shows in the book on em-6 that the pointing arrow points to the first notch on the bottom pulley, but i'am sure that last time i set it on number 2 notch, i'am sure 30psi said to use numbur 2 notch as well if so why is this.
