That is untrue as the performance of the private GPU miner was limited by the increasing scratchpad size which is now effectively much greater in size than nearly a month ago. The ever increasing scratchpad size decreases the performance of the privite gpu miner by each passing day.
So in other words the private GPU miner(s)
had a huge early advantage that can never be replicated by anyone ever again in the future. Sounds
exactly like an instamine to me.
