Concerning the trigger, it seems pretty clear : Cannot allocate a single /22.
The second, I would rewrite into "What is the amount of recovered space every year? When does recovery happens (all year or specific period of the year) ?". Plus estimations for the future if any.

However there are some questions on what does the NCC do *before* getting there.

Let's remember there still are temporary allocations. How much space do they usually take out of the /13 reserved for them ? Should be move temporary allocations to standard pool (and merge their pool into the main one) ? If yes, when ? Now ? When there are no more /22 in the regular pool (preventing the switch to /24 for a few months) ? when there is only /xx (/13 suggested) free space in the regular pool ? Do we need a policy for that of is it just "NCC bookkeeping stuff" ?

There's the quarantine (returned/recovered blocks) : what happens when there's not a single /22 in the "free" pool, but there is space in the "Reserved pool" (quarantine + temp allocations).

That's about 10 questions. An answer before the impact analysis (I'm confident this will at least reach "impact analysis") would be greatly appreciated.

I will be able to give an opinion based on the answers to those questions. For the moment I'm half for (because the waiting list is something that will be needed at some point in the future), and half against (the "let's end the IPv4 madness" stuff).
