What I am trying to say is that this will induce salary depression, because companies will never post the (very) high salaries that they pay for their (few) top performers. Companies will post their 0% - 80% quantiles (in fact, the lower number will be slightly lower than the lowest salary they give for that level, if only to give comfort to people starting at the bottom of the range), so they will post something like -10% - 80%.
