Consistency of impact factor as a rope ages?

Say you have two ropes, rope "A" with an impact force of 9 kN and rope "B" with an impact force of 7 kN. Now say you exposed the ropes to various wear and various falls (the wear and falls would be consistent between the two ropes), would the impact force of rope B remain symmetrically lower then rope A after and during such use?

Obvousaly the impact force of a rope on its first fall is not nearly as important as the impact force of the rope after "X" amount of usage because only your first fall is on a brand new rope. The next 1,500 falls are on a used rope.

Also how does the impact force of a rope change over usage? Obviously it rises but by how much? Would a rope that is at the end of its life still pass the 12 kN maximum impact force requirement by the UIAA or does the impact force rise that much over usage that the rope will not?
