Since we don't know the location of the troubled rib feet, and if the troubled feet are repeatable from wing to wing, aircraft to aircraft, it is hard to know for sure.
On Jan. 6th, Charles Champion, Airbus head of engineering, stated while discussing the cracks
"We found it is very random. We actually found them on ribs across the wing and from one aircraft to another it can be a different rib foot."
"On some aircraft we found almost none and on others we found several across the wing on both sides."
