If someone needs a quick list of sources on this policy angle, the references could save time.\n\nThe soft spot is that the opening claim of no statistical basis is presented as fact but rests entirely on the external documents; the paper itself supplies no specific statistical argument, derivation, or targeted critique of the metrics' assumptions. There is also no new empirical check on outcomes when metrics are down-weighted versus when they dominate. The work stays at the level of synthesis rather than adding evidence.\n\nThis is for administrators or policy people who want a compact pointer to the critical literature rather than for researchers looking for fresh methods or measurements.
