Gary:
Adding small portions of new shot to the existing batch should not have a significant impact in Intensity variation. Even though AMS 2430 and AMS 2431/1 do not cover media conditioning, you are not prevented from having an internal conditioning procedure when a batch is completely replaced with new shot. We will certainly recommend to the committee adding a paragraph to the AMS specs related to this topic. Conditioning of new shot will add quality value and consistency to the process.
