This does sound interesting, and further helps fine-tune any tail-end 
disparity that
exists following the final IANA allocations.

However, I believe the value of this would be weakened by having this 
policy implemented
too frequently, e.g. if the fastest-allocating RIRs need to do this more 
than once, or
if a slow-allocating RIR is "hit" more than once.

I would point out that this policy applies *after* the IANA reserve has 
been allocated.

The other policies under discussion apply *before* the reserve has run 
out, and concern
when and how the final IANA blocks are allocated to RIRs.

As such, the two kinds of proposals are orthogonal.

And, in fact, if both kinds are implemented, the benefit is greater than 
if only one or the
other were implemented.

As such, I would have to encourage support for both the "pie" proposal, 
this "cooperative" proposal.
