I think I should clarify the policy and the contents of the pool because I
don't want the RIPE or other communities to be surprised when the policy is
implemented. 
 
The policy
(https://www.icann.org/en/resources/policy/global-addressing/allocation-ipv4
-post-exhaustion) requires us to split the contents of the pool into five
equal parts and then round down to the nearest CIDR boundary. The pool
(https://www.iana.org/assignments/ipv4-recovered-address-space) currently
has just short of five /10s, which means the size of the allocation units
must be rounded down to /11 equivalents.
 
This is based on the current contents of the pool. If the pool size grew by
a precise amount then the policy would support the /10 equivalent allocation
unit that has been mentioned. 
 
If that does not happen the contents of the pool are likely to be eked out
in increasingly small allocations over a number of years.
 
Kind regards,
 
Leo Vegoda
