Kind of an odd assumption that dependence on luck varies from player to player.
Intuitively, it strikes me as appropriate for some realistic situations. For example, you might try to estimate the performance of people based on quite different kinds or magnitudes of inputs; e.g. one applicant might have a long relevant track record, for another one you might just have a brief work test. Or you might compare the impact of interventions that are backed by very different kinds of evidence—say, a RCT vs. a speculative, qualitative argument.
Maybe there is something I’m missing here about why the assumption is odd, or perhaps even why the examples I gave don’t have the property required in the paper? (The latter would certainly be plausible as I read the paper a while ago, and even back then not very closely.)
