OK since I work on cylinder heads all day I will tell you that the engineers dont design for equal wear but minimum wear within the cost constrants of the design. Some materials or coatings that work great are just to costly to use.
They will run new designs long enough to measure the wear so as to come up with the recomended check/adjustment interval
