In May last year I ran the software through a sequence of 12 allocations and I 
have attached a small zip file with the outputs so you can see how the pool 
roughly halves at each scheduled allocation. As required by the policy, the 
size of the allocation drops as the pool is reduced, so the allocated space 
drops from a /12 (or equivalent) to a /13 (or equivalent) and then a /14 (or 
equivalent) and so on.

Each RIR received[1] a /12 in September 2014, so the March 2015 allocation is 
likely to be a /13 (or equivalent) unless a significant contribution is made 
to the recovered pool or a significant withdrawal is made by the IETF through 
assignments made in one or more IESG approved RFCs.

Hope that helps.
