Does anyone have the time or skills required to follow all the burnt BTC at the 1CounterpartyXXXXXXXXXXXXXXXUWLpVr address back through the history of the blockchain to see when they were mined?

It would be nice to visualize the timespan over which the POW period of Counterparty occurred. Afterall, you can't have Proof of Burn without Proof of Work (in this case).
