Correct pattern for 6 nails


#1

I don’t have the Certainteed 8th edition in front of me… so I need some help from ya’ll:

Using Certainteed Landmark Premium soon, what is the correct way to nail 6 per shingle according to spec?
Is it:

  1. 6 spaced evenly (highly doubt)
    Example -->> * * * * * *

  2. Double up the ends
    Example -->> ** * * **

  3. Double up the middles
    Example -->> * ** ** *

Thanks!
