Thanks. I spotted checked your data. Two problems. First, conclusions from 2011 are woefully ancient. Second, your data is wrong e.g. ams-ix you note as 617 and there current count is 680.There are quite a few other inaccuracies contrasted to more mainstream data sources. Still, it's irrelevant.

The allocation unit compromise is making allocations from sparse boundaries no shorter than a /22 IMHO. Where does this /15 come from? Existing free pool would make sense to me.
