[arin-ppml] NRPM 4.10 - is a /10 large enough?

If I'm not mistaken the reserved /10 for IPv6 deployment and /16 for
micro-allocations is not included in the counter. Could staff confirm
Further, there is an additional approximately /10 that will come from
the IANA recovered address pool. I'm comfortable with this being
reserved for special purposes, if we see fit.
However, I'm not comfortable with reserving more out of the current free
pool at this point. We are well past the point where making that kind
of change can occur without causing potentially bad side effects. Any
drastic change in what is available for normal allocations at this point
is likely create a panic.
We discussed this as a community, there were proposals to reserve larger
chunks including the whole last /8 as RIPE and APNIC did. We chose this
strategy. In some situations never is better than too late.
My best advice is find your towel and DON'T PANIC!

I was looking at Geoff Huston's graphs (http://www.potaroo.net/tools/ipv4/) and noticed that both RIPE and APNIC, by coincidence, will be using up the first /10 out of their reserved /8s at about the same time, near the end of this year. A naive calculation says that APNIC will go through the /10 in about 3.5 years, and RIPE in about 2.2 years. Of course it is difficult to predict how the runout of the reserved /10 under 4.10 will look, but I think it's reasonable to assume that it won't be any slower than 2-3 years, since unlike RIPE and APNIC there's no limit to how much space an entity can receive under 4.10, only the pace at which it can be handed out; assuming the maximum rate, a /22 can be issued to someone every two years,
