Agreed, if the book had a higher grade it would likely have sold for more (irrespective of the "PQ" on the label ).
But it's my understanding that, in these low grade ranges, the grade is not hit further for the "PQ" on the label. Can you have a natural 9.0 that says "brittle pages"? Probably not. But a low grade 1.8? Yes.

Then I am Happy I can help you with your understanding then
At some point a book can't grade any lower (.5) so pq can't affect it more. But a book that is a 1.0 with brittle pages would be higher if pages were better. A 1.8 with brittle pages would grade higher with better pq, etc. That is a fact...just ask cgc ... So in every grade above the minimum, the pq factors in when brittle
Not to belabor the point , but I would be curious as to your thoughts on this book, which has both a detached cover and "brittle pages" on the label, and still got a 2.5...

4.0 is highest a detached cover can grade, I believe
So the brittle pages lowered it to a 2.5 all else equal
