As requested –

As far as ARIN staff can ascertain, no ISP/LIR has yet qualified for an additional allocation 
based on having used enough of their existing allocation to qualify for more.   There have 
been some additional allocations under other circumstance, e.g. 
-          Multiple Discrete Networks (I have a /32, I’m opening a second autonomous site, I need more)
-          “Do-over” (I got a /32, I did my addressing plan, I now realize I need a /28)
-          Downstream ISP customers (I have a /32, I have a downstream ISP customer,
           therefore I need additional space so I can assign them a /32)
Regarding reassignments:  there are 3,346 IPv6 direct allocations. Of those, 283 (8.5%) have one 
or more reassignments.  For comparison, there are 20,217 IPv4 direct allocations. Of those, 10,230 
(50.7%) have one or more reassignments.

May you find this information useful in your policy development efforts!
