You mean the skier is inconsistent.
One pair of after bangs isn't different from another. Maybe one in 500 might have a defect (wild guess). You might run the tip into a rail and it might snap. Next pair you dont run the tip into a rail and it last for 5 years.
LJ goes threw way more pairs of skis a year then I do but he is also going way bigger then me.
Its the person not the product.
