Just a guess, but I think he was one of the first to get a refund. The first few payouts were a lot larger to a lot fewer people. This coming from someone much further down the list.
This. My first three payments were like 1 BTC each, all of which happened in the span of one week. Then .5 and .25 every few weeks...now it's down to .05 each payment, every 5-6 weeks or so. Those of us who requested refunds the day he showed up here, willing to make repayment, were a relatively small group and payment was a lot faster. Suddenly, the list is a mile long and people demanded that he make smaller payments to more people. So here we are.
Hopefully, as the "little guys" get paid in full, those with larger amounts owed will start seeing more frequent and/or larger payments.
This answers the question.
