I can't see it being less than 5. The cover looks solid, but you never know unless you actually see the tears.
If you're planning resubing for blue or yellow anyway, you might as well crack it out and check out the torn pages. You may get lucky when you resub and end up with OW instead of CROW designation.
The seller described it: "a small piece was off upper right corner on pages 7,8,9,10,11 that barely touched into panel"
A side note, how is the tear on an odd number of pages? Each page should have two page numbers, and I'm sure it's more than 11 pages long.
