For the MP3 product, we understood that we had to control every aspect of design, development andmanufacture given that this would be a product used mainly in remote areas for education.
There is almost as much statistical noise in the wettability of the paper and the leaf from one bag to the next as there is in dissolution rates, and small changes in manufacture usually matter more than anything the consumer on the teabag side can control.
But to exert such control necessitates a repression that will not be long tolerated if the regime does not manufacture external and internal enemies that serve to justify it.
