I think we should leave those definition of what an overpurchase is to the buyers, who will have a range of intended purposes, projected growth rates, planning horizons and other considerations. At least with a cap of some sort we limit the overpurchase risk to overall address usage efficiency.

What percentage of the spectrum did each company have to buy to have that effect? A /12 maximum would limit any one org to 0.02% of the total IPv4 space before needs justification kicks in.  

There are other valid concerns here, but I think the /12 limit does address the concern about anticompetitive behavior.
