“How many Elo levels until diminishing returns on effort” seems like a sensible idea, and might work on humans as well as computers. But I still think coin-chess and poker show that using win probabilities to infer rating differences (as Elo does) isn’t very meaningful, it’s better to look only at the binary fact of whether Alice wins against Bob more than half the time.
