As of now, it makes no sense to me.

It says perception = 65 for HQ item. That makes you think (well, I actually first thought so) that having exactly same amount of perception will give you higher chance of getting that item in HQ (or something of that kinda). Seems not. Chance was 1%. From the looks of it, it means minimal needed amount of perception to at least have chance of getting this item in HQ. In this case, it kinda should be ≥ instead of =. Just = is kinda confusing.
