I'm starting to believe this is nothing more then marketing. It was obvious they needed to improve yields on their Caviar Green and I'm speculating that this was part of whatever problems they fixed. Now they are marketing it as the "new and improved Caviar Green!". It probably won't be better then the Black because if it did they would be using it for the Black and charging a higher price for it. But I'm just speculating on all of this. We still have to wait for benchmark results.
