[ ... ] Findings 1- This proposal fairly takes into account addressing hierarchies used in large and extra-large registries and introduces a useful level of flexibility for those registries. 2- The Local Internet Registries using the 80% criteria may continue to do so and will not be impacted by the new policy. 3- Complicated calculation or administrative burden should be easily avoided to registries choosing this method using simple chart or software through LIR portal. 4- As analysed by APNIC, the impact on address consumption is limited to a maximum around 20% and can be easily controlled and monitored using a rather conservative approach (AD ratio of 0.966).

Up to this point it sounds reasonable and well-balanced to me,

5- This impact can be partly counterbalanced by reducing the number of small and extra-small registries whose existence is only justified by management overhead of large registries with current 80% criteria, and has a positive impact on address aggregation.

but that particular reasoning in "5-": "whose existence is only justified by management overhead of large registries..." seems to be slightly off the mark?

6- No additional impact on registrations is seen in RIPE region, as infrastructure assignments are already registered in the database. [ ... ]
