>> I understand that these flip disk thickness are well within established spec (to such extent that even those a few sigma off will still remain < max tolerance) <<To add to this, it would not be difficult to ‘weed-out’ any out-of-spec disks, in-process, on the production line (if indeed any unacceptable dimensional variation did occur) using basic metrology equipment at the final-inspection stage. Then there would be zero out-of-spec discs released from the factory.
Actually, a pressing operation such as is used for audio media would probably show a gradual and predictable thickness shift within the tolerance band, which could probably be foreseen and prevented using SPC techniques ("statistical-process-control", or "six-sigma" etc), so the operator would know when to reset the machine, and start a new batch, to eliminate any shift to outside the allowable tolerance band.
I doubt Barry Fox has really studied SPC ( "Six-Sigma" — is what GE likes to call it).
