>One would approach peak X as you become more senior, but you would accelerate toward peak X more quickly at first But the curves are basically the opposite of this. They show less horizontal movement at the junior level than the senior level. The "peak X" you are looking at is not what it appears, you are seeing a "peak seniority" level on each graph and the "skill gain" or whatever is accelerating towards infinity as you approach the most senior person (which you can never reach...?)
