2009-8 (which added the 90 restriction on ISP initial allocations) indicated "This reduction does not apply to resources received via section 8.3.”, and therefore it is inappropriate to take it into consideration when comparing allocation policy against transfer policy as it was never indicated to apply with respect to transfers.
